In the new section on Conic Sections, Dr. Eaton first begins with the Midpoint Formula and Distance Formula. After describing the formulas and several examples, you are able to work on your own with four additional exercises to make sure you can use both formulas appropriately.
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.
