Question
The graph provides a good approximation of the number of drive-in theaters in the United States from 2000 through 2007.(a) Use the given ordered pairs to find the average rate of change in the number of drive-in theaters per year during this period. Round your answer to the nearest whole number.(b) Explain how a negative slope is interpreted in this situation.
Step 1
The slope of a line is given by the formula: \[ m = \frac{y_2 - y_1}{x_2 - x_1} \] where \( (x_1, y_1) \) and \( (x_2, y_2) \) are the coordinates of two points on the line. Show more…
