A simple line graph. The y-intercept in this case is 2.

The y-intercept of a line on a graph is where the line touches (or intercepts) the y-axis (the numbered line going straight up). If the equation of the line is y = mx + c, the y-intercept will be the point where x = 0. Because 0 * anything is just 0, y = c. This is why c is the y-intercept.
