Finding the Slope of a Line from a Graph - Concept

Explain how to find the slope of a graph of a line with a video that points out how no matter what two points are used on a graph of a line, the slope is the same. A few examples reiterate how to find the slope of vertical and horizontal lines, which helps tie everything together for the viewers.
