This resource has been contributed by Winpossible, and can also be accessed on their website by clicking here - Determine the y-intercept from equation of a line (y=mx+b).

It shows how to determine the y-intercept of a line if you have been given its equation. In the equation y = mx + b, the constant b is called the y-intercept, and is the y-coordinate of the point at which the line intersects the y-axis. Hence, to find the y-intercept for any given equation, rearrange the equation into the standard form y = mx + b, and b will give you the y-intercept. The mini-lesson also explains how to graph a line after determining its y-intercept.
