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) $ per pound
The rate of change (slope) of a linear graph can be found using the formula:
slope = (y2 - y1) / (x2 - x1)
Given that the points are (3,8.25) and (6,16.50), we can plug the values into the formula:
slope = (16.50 - 8.25) / (6 - 3)
= 8.25 / 3
= 2.75
Therefore, the rate of change in the purchase price is $2.75 per pound.
