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)
To find the rate of change in the purchase price in dollars per pound, we need to find the slope of the line that passes through the given points.
The slope of a line can be found using the formula:
slope = (y2 - y1) / (x2 - x1)
Using the coordinates of the given points:
x1 = 3, y1 = 8.25
x2 = 6, y2 = 16.50
slope = (16.50 - 8.25) / (6 - 3) = 8.25 / 3 = 2.75
Therefore, the rate of change in the purchase price in dollars per pound is 2.75.
