Question 1084630: Find the slope then describe what it means in terms of the rate of change of the dependent variable per unit change in the independent variable.
The linear function f(x) = -8.7x + 38 models the percentage of people, f(x), who eat at fast food restaurants each week x years after 1998.

f%28x%29+=+-8.7x+%2B+38+
slope is m=-8.7; the percentage of people eating at fast food restaurants each week has decreased a a rate of -8.7% per year after 1998
