NettetLet's practice finding intercepts and zeros of linear functions. There are two types of intercepts: x -intercepts and y -intercepts. When you write an equation in slope-intercept form, the y -intercept is listed as b. The y -intercept is where the graph crosses the y -axis. y = m x + b The x-intercept is where the graph crosses the x-axis.
