how to write the equation of a line in y=mx+b form with two given points

[@twelfthdoc]

Worth remembering that the point/slope equation also works when you use (x2, y2) instead of (x1, y1), as we are finding the equation of the line which has both of these points on it. If one set of coordinates looks difficult and the other looks easier to manage, it will still lead to the same slope/intercept version of the equation :)

And for the slope coefficient m it doesn't matter if instead [Y2-Y1]/[X2-X1] or [Y1-Y2]/[X1-X2]

Love your videos. FYI. In Australia, most textbooks use +c (constant) instead of +b for the y-intercept

[@turtlebro8314]

Same for uk!

In Hungarian we call slope as meredekség, so we can assign a meaning to m in the equation

[@holyshit922]

m=tan(alpha) so if slope is undefined line is perpendicular to X axis

I watched this video at 1.50AM in India 🇮🇳. I really love your videos and your teaching style.

U saved me man frrr

I do not know if it is coincidence but slope in Arabic is Mail ( ميل ) which start in m ( but also Algebra is Orginaly Arabic word )

Thanks a lot, this can serve me in my math classes.

Number 2 example when you said a number I thought you were going to say it’s just a constant

[@letranger3581]

do the same for the quadratic function pls

4:50 am in the Philippines, and I am watching this. Cheers👋👋👋

Huh?

[@abdoboujarat9737]

But in the other functions we need to use calculus 😆
