Average Yearly Mileage for Passenger Cars in the United States in the year 2005 Let y represent the average number of miles driven per year for commuter cars in the United States since 1980.
Let x represent the year where x = 0 corresponds to 1980, x = 1 corresponds to 1981, and so on. The average yearly mileage for rider cars can be approximated by the equation y = 142x + 9060, where x ≥ 0. Use the linear equation to approximate the average yearly mileage for passenger cars in the United States in the year 2005. What is the slope of the line and what does it mean in the context of this problem? What is the y-intercept and what does it mean in the context of this problem?
