A linear graph of the cost of broccoli in dollars per pound has the points (3, 8.25) and (6, 16.5) What is the rate of change in the purchase price in dollars per pound?
(1 point)
per pound
The rate of change in the purchase price in dollars per pound can be calculated using the slope formula:
slope = (y2 - y1) / (x2 - x1)
Given the points (3, 8.25) and (6, 16.5), we can substitute the corresponding values into the slope formula:
slope = (16.5 - 8.25) / (6 - 3)
= 8.25 / 3
= 2.75
Therefore, the rate of change in the purchase price in dollars per pound is 2.75 dollars per pound.
