(3 of 3) Basics of Slope: Calculating using the Slope Formula ... MathWOEs

The last video in our series on slope basics essentially derives the Slope Formula (given two ordered pairs, find the slope algebraically), based on the initial concept of "rise over run."

We then go on to show the use of this formula both based on a graphed line (the formula is a bit of overkill if you can see the graph of the line), and finally on just two ordered pairs with no graph.
