## Change the positions of points A and B. What happens to the value of the Rate when you change the position of the points? How does that connect to the behavior of the graph of f(x)?

## Description

This applet introduces average rate of change. Students look at the position of the points and how that changes the slope of the line segment connecting A and B. They should be able to see that the graph of f(x) is increasing and decreasing when the slope of line segment AB is positive and negative respectively.
