Point-Slope Formula
Writing an equation of a line using Point-Slope Formula
Here are two ways to derive the point-slope formula.
1. Suppose we have a line. Then we have

In particular, suppose we have a point on our line, (x
, y
), but we allow

a point (x, y) to be any other point on our line. Then the slope of our
line is given by
