Slope Formula and Example

            y2-y2
slope= x2-x1

Remember that the points are always listed (x1, y1) (x2, y2)

Example:

(1, -19) (-2, -7)

First plug the numbers into the equation.

-7-(-19) = 12
-2-1         -3

Now simplify the answer, think, 12 divided by -3 equal -4.  The slope is -4.
