For this example, there is no x intercept, this is just a horizontal line at -2.5. The y intercept is -2.5. In general, if you have y=(some number) you get a horizontal line at that number, that number is your y intercept, and there is no x intercept. If you have x=(some number), then you have a vertical line at that number, that number is your x intercept, and there is no y intercept. Try drawing it out. Anything you are asked to graph will involve x, y or both.
