All lines except for horizontal lines have an x-intercept. The x-intercept is where the line crosses the x-axis. See the picture on the right.

- An x-intercept of 5, means that the line cross the x-axis at 5, which is the point (5, 0)
- An x-intercept of -2, means that the line cross the x-axis at -2, which is the point (-2, 0)
- An x-intercept of 3, means that the line cross the x-axis at 3, which is the point (3, 0)
What is the x-intercept of the line in the graph below?
The x intercept is 2, or, more specifically, it is the point (2, 0).
