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)

The rate of change represents the slope of the linear graph.

Using the two points (3,8.25) and (6,16.50), the slope can be calculated using the formula:

Slope = (change in y) / (change in x)
Slope = (16.50 - 8.25) / (6 - 3)
Slope = 8.25 / 3
Slope = $2.75 per pound

Therefore, the rate of change in the purchase price of broccoli is $2.75 per pound.
