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
To find the rate of change in the purchase price in dollars per pound, we need to find the slope of the line passing through the two given points.
The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula:
slope = (y2 - y1) / (x2 - x1)
Using the given points (3, 8.25) and (6, 16.50), we can substitute 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.
