- 👉 Learn how to write the equation of a line that is perpendicular to a given line. The equation of a line is such that its highest exponent on its variable(s) is 1. (i.e. there are no exponents in its variable(s)). There are various forms which we can write the equation of a line: the point-slope form, the slope-intercept form, the standard form, etc.
When given a point (x, y) through which a line passes and the slope (m) of the line, the equation of the line is given by y - y1 = m(x - x1). For perpendicular lines, the product of their slopes is -1. Thus given the equation of a line and a point through which the line perpendicular to the given line passes, then the slope of the second line is equal to the negative of the reciprocal of the slope of the given line. Having found the slope, we can then use the formula stated above together with the given point to find the required equation.

This video was released 7 years ago and It's still helping us in 2019.
Thank you so much for uploading.
ッlemons nice profile pic
You must be a 10th grader as well
IM THAT PRETTY BOY I think most of us are
Robert Hodges lmao so am I
Rp2I Gaming nah I’m in 12th
This man has been saving kids from failing finals since 2012
@StupidWithAPhone
bro same- it’s a big unit test and i did not pay attention at all :D
the internet has been making me pass classes since 2017
Here 2020
When a 5 minute lesson teaches you more than a 45 minute lecture
wow
Ani I play Tetris in class and then watch this vids
Ikr
They cut to the chase

How can I enroll in your class? you've taught this so much better than my teacher.

The best math teacher ever.
In only five minutes he made my life easier.
well you explained it better than my math teacher thank you Brian much appreciated!
you are very welcome!
i zoned out when my teacher explained it, thanks for explaining it!
Nice name lmao
@@Iemons why thank you :)

Hi
@@Duckz57 hello cat
3:53 dang John I’m tryna learn
Darn it John why are you delaying us
@@10k- wasnt he just correcting the teacher doe
You see, when a teacher can simply help a student by giving them a 5 minute review on things they did in the past, they can remember longer. My teacher thinks we know this by heart, but I just can’t because it’s hard for me. So these videos help me so much to get the review I need so I can not fail a simple assignment review. Thanks man.
Thx so much !! I understand how. At first I forgot how to do it but then it came to mind little by little !! Now Ik how to solve it
Who is that kid talking in the background he needs to quiet im trying to learn
😂
thank you so much, when I'm doing last minute revision, I click on your channel.
12 years later and this still helps!
I wish u were my math teacher!! thank u so much sir
Mother of a grade 9 boy student saved again by, yet, another excellent math lesson/explanation. Thank you!
Thank you, this is a lot easier now
Thank you! Very clear and concise
Legend, hands down. America rockin' it out here. Thanks for real.
you are very welcome!
Thank you so much for this!! I've been procrastinating on an assignment for a week and a half simply because I didn't understand how to this one peculiar problem. This helped me solve it.
Thank You Mr.McLogan I have a quiz tomorrow on this topic. I feel really confident on passing!!! :)
Same dude
hey dude how did you do on that quiz
man you are so helpful, my textbook is just too defective to even teach this basic level of mathematics. Thank you very much!
God bless you.. my teacher doesn't wanna teach so I gotta teach myself and this was so clear and straight to the point!
Thanks! Really helped me understand this topic better.
This really helped me out with my homeschooling, TYSM
Your 5 min video is better than my teachers 90 min class
This helped me very much thank you for teaching me
you did this video years ago and its still helping people to this day thanks
happy to be able to help
And as school starts again we return to this mans channel and understand more than when our teachers teach us
Brasil - excelente aula professor!
Give this man a medal already.
march 24, 2020 at 1:15 am and corona blessed me w you gracias
Thank you for helping.
You are better than my teacher thx
@TheBuckeyboy thanks!
Man! This dude is a life saver! Mans has been saving me for years!
Hello sir! I hope you're doing great. Appreciated a lot this video since this helps so much, in fact I was shock to know that this was posted 9 yrs. ago. Thank you.
Thx for the video dude really helped me. I'm a 7th grader taking it 2 years early, so I'm kinda struggling. Now I will pass this quiz🤓
same
thanks for helping we study for a test the day before
Thank you. I'm so glad TH-cam exists
I wish you're my math teacher!
You’re an angel man thanks for helping me do my math homework
I am from India but I generally follow you
I worked for a short time as an unregistered Vet Tech, with plans to work Part-time & go to school to get Licensed. I postponed those plans to take care of my terminally ill Mom. I saw the info from ABC & started the initial steps to request some basic information. You know name,address phone # & the program that interested me the most, so far. Kinda hard to determine which program interested me the most without any information at all outlining the actual programs themselves. However I picked one. Next came contact information for how to text me. I AM NO LONGER INTERESTED IN YOUR "COLLEGE"
he such a big help cause my teacher does not know how to teach.
I prefer the point slope method, but this was clearly explained also, thank you!
I do to, but here is another example
Thank you so so much, I understand so much better now
Your a great teacher 🙏🏻
thanks so much I have been watching your videos and helped me a lot in my test thanks
Its safe for me to say but your saving lifes lol but for real thank you for the amazing videos they are super helpful💯
Happy to help Luis!!!
Thank you so much, I was stuck on that ‘opposite reciprocal’ thing
you are the best u made that so much easier like fr thank u that 5 min video better than 2 classes with my teacher
Helpful. Thank you.
you are very welcome!
Thank you sir, I'm trying to learn these lessons in English, really helpful, thanks!
you are very welcome!
very nice thank you my teacher explained it once and asked for 10 problems for hw
This man is litterly saving my life
Thank you man you are the reason i am getting better !
So how do you pull this off when you have variables mixed in as well? The coordinates look something like this: (2a, 6ab), (5a, 8) and (5a, 0), (-6b, a). I have to determine whether the lines or perpendicular or not and I'm extremely confused as I've never seen anything like that before.
Omg u helped me understand a BIG part of my exam tomorrow, thank you so much!!!
I hope you fail
Holly Dickson nobody asked for that-
@@hollyblaylock8199 ?
YOUVE SAVED ME TWICE ON MY HOMEWORK BY NOW THANK YOU
You are very welcome!!
Thank you so much this video was very helpful.
You are my second professor!
tfw a 5 minute video is better than 3 ,1hour class discussions
It's more easy through slope point form for me! As you explained in other video
This really helps during online class when nothing makes sense
I'm working on a problem trying to find the perpendicular lines. When I carry over a fraction to the other side, do I convert that fraction into a decimal, or do I simply put a one over the number on the same side and do the arithmetic?
Thus video helped me a lot thank you :)
Wouldn’t the opposite of x be - 1/x since it’s original from is x/1 (x)
No, his original slope was 1x, but the 1 is the slope, not the x. X is just x. Therefore the opposite reciprocal slope comes to -1/1. Hope this helped. :)
Thank you very much! This helped me a lot. I now understand it :D
I am glad you had good comments. You said two or three things that were not accurate but I guess. I always watch before showing and sharing ro my students. I am supposed to be making videos but yours are helpful to share so I keep procrastinating.
3:10
2:07 not a biggie but can confused some
2:32
thank you mr Mclogan
Thank you !
God bless you for this
Thanks for saving us even in 2024
Is this taught in pre calculus?
Pov: It's been 10 years and you're still saving lives
hey mr.mclogan this eronde i really liked your video
I got it now! Thank you!
you are very welcome!!
This dude is good.
You're saving us over online teaching my god
10 times better than my algebra 1 teacher good for review
awesome! happy to be able to help!
Why do you plug in the values of x and y
Thank you
you make my mathematical life easier
This dude carries my math grade.
Thanks, this helped a lot
Can anyone help me? The question is: find the equation that passes through point (3,4) and is perpendicular to the given line.
3x+2y=10
3x-2y=4
DID U NOT LISTEN TO THE GUY??
Can you use point slope formula once you know the slope?
yes
the best one simple one and fast one
Happy to help!
Thank you. So helpful
you are very welcome! happy to be able to help
John is quite the character
Lol ur better that my algebra teacher
You're the best
My mom said " This teacher should teach for Amazon Great Courses "
Thanks bro
So helpful thank you
you are very welcome Adee!
U just helped me
I’m watching this before my test
thanks
all he said was opposite slope and i solved all the multiple choices problems
For the y intercept we just do x=0 and it’s faster that way
Yep
Help tough math problem:
Write an equation in slope intercept form for the line that
passes through the given point and is perpendicular to the graph of the
equation.
(-2,3),y=-1/2x-4
