Chapter 2.4, Problem 14PE
Let y represent the average number of miles driven per year for passenger cars in the United States and let x represent the number of years since the study began. The average yearly mileage for passenger cars can be approximated by the equation y = 142x ± 9060, where x > 0.
a. Use the linear equation to approximate the average yearly mileage for passenger cars in the United States in year 25.
b. Use the linear equation to approximate the average mileage for year 5, and compare it to the actual value of 9700 mi.
c. What is the slope of the line and what does it mean in the context of this problem?
d. What is the y-intercept and what does it mean in the context of this problem?
