A city is paving a bike path. The same length of path is paved each day. After 6 days, 15 miles of path remain to be paved. After 9 more days, 12 miles of path remain to be paved. Find the average rate of change. mi/day

Use the average rate of change to write a linear model that relates the distance y (in miles) remaining to be paved to the number of days x.
