The x intercept is always the point where the y-coordinate is zero, and the y-intercept is always where the x-coordinate is zero. If you're given an equation only, find the x-intercept by substituting in y = 0 and then solving for x. There is often more than one x-intercept, and sometimes none at all. Find the y-intercept by substituting x = 0 and solving for y. There is usually not more than one y intercept, and sometimes none at all.
