The Y-Intercept of a line is the point where a line's graph intersects (crosses) the Y-axis.

- A y-intercept of 3 means that a line's graph intersects the Y-axis at the point (0,3).
- A y-intercept of -4 means that the graph of a line crosses the Y-axis at the point (0,-4).

**Example** of the Y-Intercept

In the diagram on the left, the y-intercept is 2 which is the point (0,2).

**Practice** Problems

The Y-intercept is 3 or the point (0,3)
