All lines except for horizontal lines have an xintercept. The xintercept is where the line crosses the xaxis. See the picture on the right.


Examples
 An xintercept of 5 , means that the line cross the xaxis at 5, which is the point ( 5,0)
 An xintercept of 2 , means that the line cross the xaxis at 2, which is the point ( 2,0)

An xintercept of 3 , means that the line cross the xaxis at 3, which is the point ( 3,0)
