So let's substitute one of these points in here, to figure out what our b must be. And once again, I want to figure out something where this is going to become nice and clean.

Graphs of linear equations and functions: Slope-intercept form Learn Intro to slope-intercept form

Sal finds the equation of a line perpendicular to a line given in slope-intercept form that passes through a specific point.

Given two points on a line, we can write an equation for that line by finding the slope between those points, then solving for the y-intercept in the slope-intercept equation y=mx+b.

When an equation is written in this form, m gives the slope of the line and b gives its y -intercept. Want to learn more about slope-intercept form? Check out this video.

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form. We review all three in this article.

So whenever you look at an equation in this form, it's actually fairly straightforward to graph this line. b is the y-intercept. In this case it is negative 2, so that means that this line must intersect …
