2. 1. The great runner could travel 10 miles at 5 mph and then run 6 miles at 2 mph. What should be her speed for the next 8 miles so that her overall average speed would be 4 mph? The data points in the table below relate the number of textbooks sold (S) to the price per textbook (P). Note that in the graph the horizontal and vertical scales are different. The position of the line that best fits this data has been estimated. Write the equation that expresses the number of textbooks sold as a function of the price per textbook (S=mP+ b).
