A linear graph of the cost of broccoli in dollars per pound has the points (3,8.25)

Question

and (6,16.50)
. What is the rate of change in the purchase price in dollars per pound?(1 point)
$
per pound

Answer 1

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 given points.

The slope of a line is given by the formula:
slope = (change in y-coordinates) / (change in x-coordinates)

In this case, the change in the y-coordinates is 16.50 - 8.25 = 8.25 and the change in the x-coordinates is 6 - 3 = 3.

So, the slope (rate of change) is 8.25/3 = 2.75 dollars per pound.

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