To determine the constant rate of change for the total number of books sold in the bookstore based on some points on this graph (0,0), (2,1000), (4,2000), and (10,5000), we will calculate the slope between consecutive points.

The formula for calculating the slope between two points and is:


Let's calculate the slope between each pair of points:
Between (0,0) and (2,1000):
