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 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.
