X & Y Intercepts

​The X-INTERCEPT is where the graph crosses the x-axis. It occurs where y=0.

​

​​The Y-INTERCEPT is where the graph crosses the y-axis. It occurs where x=0.

​

​Standard form of a linear equation is especially helpful for finding intercepts! (Recall: standard form is ax+by=c.)

​x-intercepts: Plug in y=0 and solve for x

​

​y-intercepts: Plug in x=0 and solve for y.
