Algebra 20 - Slope-Intercept Form

Linear equations of the form y = mx+b can describe any non-vertical line in the Cartesian plane. The constant m determines the line's slope, and the constant b determines the y intercept and thus the line's vertical position.

Today I understand why we add b thank you so much 😢❤

"Every point on this line has a y-coordinate whose value is one greater than the value of its x-coordinate".
If the value of b is, let's say 23, is that mean the value of every y coordinate on the line, on the graph, is 23 greater than every x coordinate in every point? thank you.

I'm so thankful for Why U. Love the videos on math. It's hard to find a comprehensible curriculum for a 6th grader who's in Algebra. :D. Can't wait for the 22nd episode!

soooo gooood keep it up:) basically going to be my teacher till the end of highschool

"Once again, this is because.
the y-coordinate of every point on the graph is three units greater than if we had not added three. "

Hello,
greater than what? Thank you.

These videos are great.. I just wish I'd discovered them a couple of years ago, they would have been more of help back then. Oh well, Repitition never hurt anyone ;)

This is sometimes called "slope-y-intercept-form".
