# Y-Intercept of a Straight Line

**Where a line crosses the y-axis of a graph**

Just find the value of **y** when x equals 0

### Example:

In the above diagram the line crosses
the y axis at **y = 1**

### Example:

Here the line crosses
the y axis at **y = −2**

## Point

The y-intercept is an ** (x,y) point** with x=0, so we show it like this (try dragging the points):
