1. In 2009 the number of vehicle sales in the United States was 10,600 thousand and in 2013 it was 16,280 thousand. a. Determine the average rate of change (slope) from 2009 to 2013, as measured by the average number of new cars per year (and NOT as the number of thousands of new cars per year). b. If x is the number of years since 2009 and f(x) is the number of vehicles sold, find the equation of the line through these two points. (Hint: you will need to use your result from Part (a), along with some additional data from the statement of the problem.) C. Assuming f(x) is a linear function, use the equation to predict the number of vehicles sold in 2016. 1.
