# Graphs of linear equations | Linear equations and functions | 8th grade

## By Khan Academy

A video that goes over graphing linear equations on the coordinate plane. The first part of the video starts with an equation with two variables, x and y. The instructor finds sample points and then plots them. Then, he moves on to some more complicated and conceptual problems.
