Midpoint and Distance Formulas

• Make sure that you know and understand how to use both of these formulas. They will be used in a lot of later work.

• Remember that the order of the x coordinates in the distance formula does not matter. So take whichever difference is easier to compute. The same comment applies to the y coordinates.

• After squaring the differences in the distance formula, be sure to take the positive square root of their sum.
