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)

Answer 1

To find the rate of change, we need to calculate the slope of the line that passes through the two given points.

The slope formula is given by:
m = (y2 - y1) / (x2 - x1),

where (x1, y1) = (3, 8.25) and (x2, y2) = (6, 16.50).

Plugging in these values, 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 2.75 dollars per pound.
