How to find y-intercept with two points.

If you are given a point-slope form of a line, you can get the slope intercept by following these steps: Write down your point-slope form: y - b = m (x - a) Expand the right-hand side: y - b = mx - ma. Add b to both sides: y = mx - ma + b. This is slope-intercept form! The slope is m, and the intercept is -ma + b.
