Here are the main points that will be addressed in the videos. Please read these and think about them as you watch.

These videos focus on the concept of graphing constant rate of change between two variables.
When two quantities vary at a constant rate with respect to each other, the graph of their relationship forms a straight line.
When two quantities, $x$ and $y$ , vary at a constant rate with respect to one another, the change in y is always a constant multiple of the change in x.
