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)
The rate of change is calculated by finding the slope of the line that passes through the two points.
Slope = (y2 - y1) / (x2 - x1)
Slope = (16.50 - 8.25) / (6 - 3)
Slope = 8.25 / 3
Slope = 2.75
Therefore, the rate of change in the purchase price of broccoli is $2.75 per pound.
