To find the rate of change in the purchase price in dollars per pound, we need to calculate the slope of the line passing through the two given points.
Slope (m) = (y2 - y1) / (x2 - x1)
Where (x1, y1) = (3, 8.25) and (x2, y2) = (6, 16.50)
Slope (m) = (16.50 - 8.25) / (6 - 3)
Slope (m) = 8.25 / 3
Slope (m) = 2.75
Therefore, the rate of change in the purchase price of broccoli is $2.75 per pound.
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
