How Do You Find the X- and Y-Intercepts of a Line If You Have a Graph?
The x-intercept is the point at which the line of the equation crosses the x-axis. The y-intercept is the point at which the line of the same equation crosses the y-axis. It's as easy as that. Look at your graph and note these locations.
