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

These videos focus on the concept of graphing an increasing rate of change between two variables.
When two quantities, $x$ and $y$ , vary at an increasing rate with respect to one another, then successive uniform changes in $x$ will correspond to increasing changes in $y$ .
When two quantities vary at an increasing rate with respect to each other, the graph of their relationship forms a concave up curve.
