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:

y intercept

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

Example:

y intercept

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):
