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)

1 answer

To find the rate of change in the purchase price, we need to find the slope of the line passing through the two given points.

The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula:
m = (y2 - y1) / (x2 - x1)

In this case, the two points are (3, 8.25) and (6, 16.50). Plugging these values into the formula, we get:
m = (16.50 - 8.25) / (6 - 3)
m = 8.25 / 3
m ≈ 2.75

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