a linear graph of the cost of brocoli 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?
$ _____ per pound
To find the rate of change in dollars per pound, we need to calculate the slope of the line that represents the cost of broccoli.
The slope formula is given by:
m = (y2 - y1) / (x2 - x1)
Using the given points (3, 8.25) and (6, 16.50):
m = (16.50 - 8.25) / (6 - 3)
m = 8.25 / 3
m = 2.75
Therefore, the rate of change in the purchase price of broccoli is $2.75 per pound.
