# Intercepts from an equation

Let's graph -5x + 4y = 20 from its intercepts. Intercepts are the places where a line crosses the x- and y-axes. When a line crosses the x-axis, the y value is 0. That's the x-intercept. When a line crosses the y-axis, the x value is 0. That's the y-intercept. The line passes through those points. Created by Sal Khan and Monterey Institute for Technology and Education.
