Question

A linear graph of the cost of broccoli in dollars per pound has the points (3,8.25) and (6,16.50). What is the rate of change in the purchase price in dollars per pound?(1 point)
$
per pound

Answer 1

The rate of change in the purchase price in dollars per pound can be found by calculating the slope of the linear graph.

Slope = (change in y-coordinates) / (change in x-coordinates)

In this case, the change in y-coordinates is 16.50 - 8.25 = 8.25 and the change in x-coordinates is 6 - 3 = 3.

Therefore, the slope (rate of change) of the linear graph is 8.25 / 3 = 2.75.

The rate of change in the purchase price in dollars per pound is $2.75 per pound.
