I cant describe how much the guy in this video has saved my life. he explains things in the least complicated way possible. the different colors for the variables are perfect for understanding whats in the equation relative to the physical slope on the graph.
OH. MY. G*D! IT TOOK ME 1.5 WEEKS OF WATCHING SO MANY VIDEOS. Watching this alone couldn't get my brain around it I think it was just too many subjects at once for me. THEN FINALLY a combo of a virtual worksheet and it explained to me how I did it wrong again... and well rested brain... THEN watching this video again... and I'm like.... OHHHHHH lol I made it more complicated then it should be of been. Thank you for making these videos!!! Without them I would be so lost in class. But now! I have a 96% average
Thanks for the very clear explanation. I am a semi-retired music teacher, and I am trying to learn/relearn math I haven't had in many decades. Your videos are very well-done, and very helpful.
@@nidurnevets How did your math journey go in the last decade? Did you stick with it, and if so, do you have any great books or resources for us just starting out?
@@benderpinson I did not stay with it. My aptitudes lie elsewhere, which I knew all along. I did gain something from learning more math, and find the subject interesting.
LOL! omg I was like okay cool! Like an engineer? Then I read the comments and realized you were being sarcastic. lol! my bad. I actually want to be one. So hopefully fingers cross second career here I come!

Your videos are very helpful! I honestly don't know why there are so many hate comments on the software. You're explaining everything perfectly and there are people complaining about COLORS. It's not very distracting at all, it just helps separate everything in order. I used to look at Kahn Academy and not like it at all, if im going to be honest. I think it might have just been my annoyance to get the math over with that I didn't actually concentrate on what the videos were actually saying. The only reason you don't understand is because you're rushing or you're not willing to learn (personal experience) But what im trying to say is that your videos helped me so much over the years. Thank you.
Thank you for this video, simple, short, and straight to the point. I have to catch up in my college math starting from the basics so that i can be able to take economics and get my 4.0 GPA back
its hard learning math when you don't know the names of the formula things like im trying to find the one where you get y on on side but i thought it was called point slope but it was actually called slope int...

My school teaches this a little different. Instead of using a and b for points we use y1 and x1, only the 1s are tiny little 1s by the letter but I don't how to type those. For the slope formula we use y2-y1 over x2-x1. For homework, some of the questions give us two sets of points, for example (5,1) and (3,-7) and we have to use these but it doesn't tell us which set is the ones and which are the twos and I'm not sure how to tell. Can someone help me with this?
Candy Yang So what I do back in Uganda is I use the 2nd point in the set (1 and -7) as my x2 and y2 and the 1st point in my set (5 and 3) are x1 and y1
It would help if the variable b, in the point-slope formula, y-b=m(x-a) was clarified to infact be the same variable b that is in the slope-intercept formula, y = mx+b. It took me rearranging the formula on my own to figure out that when a, the second point's x value, is zero the formula yeilds y-b=mx, aka the y intercept formula, proving the b is the same. This was very confusing and seemingly ambiguous from the video.
Why is this not making sense to me? I keep getting the same answer for the problem I'm working but it doesn't satisfy the line. In this example if you were to substitute "x" for 0 then y=19 but that isn't a point on the given line. Yet this seems to be the correct equation for the line. PLEASE HELP
Jayson Grey well here you do not need to find out the values of x and y. U just have to find the equation of a line. Let me give u an example:- suppose I have m=2, y1=3 and x1=4 Then u just have to put the value of them in the equation and u will get 5=2x-y. THAT'S IT! That's the equation of the line. Hope u know the first degree equation ax+by+c=0. Hope this helps!
Slope is defined as rise over run. Two points might be (x,y)(x',y') Rise is y'-y (delta y) Run is x'-x (delta x) Slope will be delta y (rise) divided by delta x (run). [Delta means how much greater is y' than y.]

So distracting from trying to understand ..which by the way is not going that well..thank GOD I watched Organic Chemistry Tutor on you tube and he is really a good tutor and as far as I am concerned a good teacher as well..Because this and other videos I have watched of this Khan academy is pretty bad.. I truly hate to be so blunt but really..maybe you should try teaching art class?
thank you very much. my math teacher explained this in a way that made it seem like rocket science

YES! That's the thing eh! We just need it like brought waaayyy back down lol
Lol I'm assuming you've graduated now
I went through all algebra without knowing this and I was able to learn it in 7 minutes before my geometry midterm lol
@@menace4841 Yes sir class of 2019!(Just barely LMAO!)
I want to hug you, I appreciate you, I’m glad we have people like you on earth

His voice sounds like surge
i have to agree with this
Really does help

I have a math test tomorrow and this was the last subject I needed to cover. Thanks, Sal.
Another way to look at it is y - y1 = m (x - x1)
its actually, y1 - y = m (x1- x)
Graphzi my teacher told me it’s y-y1= m(x-x1)

Thank you making this video. It made me understand point slope form a lot better.
I like how everyone watches this on the website so they don't get a chance to like this video.

KHAN academy💯, even in 2024, is one of the best math explanations out there‼️‼️‼️❤
its hard learning math when you don't know the names of the formula things like im trying to find the one where you get y on on side but i thought it was called point slope but it was actually called slope int...
Y on one side of the equals sign is y = mx+b is called slope Intercept form
No questions at all thank you!! I'm gonna surprised my teacher! Spring trap time!
My teacher's formula(idk if thats what u call it) for the point slope form is y-y¹=m(x-x¹) but its just the same for how you solve it
it's the exact same formula lmao
Way better than my teachers can explain it. Thanks a lot for a clear explanation!!
Finally something useful
Thank you so much for this, I have to take the state standardized test tmr and this is the only thing I don’t remember
also this is much better than my math teacher's explanation so thanks and I subscribed.
Thank you, Sal!
You really helped me out with a lot in my Math 1 class. Thank you so much.

You my friend, have a talent for teaching. thanks!
I've learned this like 100 times but I can't ever remember it...my guess is because I never use it
Thanks for teaching me how to do my work.
This literally helped me so much u r the best!
5a^3=40 -> a^3=8 -> a=2
I watch his videos and when I do I’m like yk what I can’t do this but when I hear his voice I’m like fuk he seems so cool
Nice sir
You make everything seem so easy...until my math teacher comes and complicates everything!
THIS IS GREAT REALLY HELPED ME OUT THANK YOU

The second ones are the 2 sets and the first one is the first sets or that atleast what my math teacher tought me:)
Same
Candy Yang please give answer tu dis question
Am here
hi, what is the difference between x and x1? and the difference between y and y1? thank you.
X and y are just variab
X1 and y1 are the specific variables that you are given
@@ezekieldruzan6350 thank you.
Thank u I didn’t pay attention in class lol
extremely helpful

You're a life saver o_o
I have 0 understanding of this and I’m most definitely failing my test
given point and slope, why is it so rare to find the equation: b=y'-x'm
(where b is Y intercept).
After all, our missing link is.... b , yes!
Good video... you might skip changing color pens all the time.. It distracts from your explanation.
Sid DL Maz Actually, it helps.
so you want to get it to slope intercept form?
Amazing I love you
But then is 5 (b) your y intercept?
Pov your doing online school 🏫
my lord and saviour.
Lifesaver 😁👌
Is it confusing to anyone else to have a multiple b s meaning 2 different things in the same example?
Instructive but near the end difficult to follow because the captions get in the way of the fractions.
Who is here in 2021 because they need to know for a math quiz
its y-y1=m(x-x1)
.
FIRST
(insert thankful comment for not failing test here)
why am I watching this instead of looking in my textbook for tomorrow's exam? 😂😂😂
I have a skills test in my math analysis class 😭😞
*today i have realized..that i am just straight up d u m b*
thats not nice :)
Which software this is
What if you arent given slope, just two sets of points
Slope is defined as rise over run.
Two points might be (x,y)(x',y')
Rise is y'-y (delta y)
Run is x'-x (delta x)
Slope will be delta y (rise) divided by delta x (run).
[Delta means how much greater is y' than y.]
(Y2-y1)/(x2-x1)
2x +19 is that a answer ?
too complicated that formula is much easier lol

*no!* dear god just *NOOOOOOOOOOO*
still dont get it and i used to like math but online learning is soooooo hard and sooooooo stoooooopid
i am having trouble finging M
m =y/x
just m= y2-y1 / x2-x1
