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 dollars per pound, we need to calculate the slope of the linear graph.
The formula for slope is:
slope = (y2 - y1) / (x2 - x1)
Let's use the given points (3,8.25) and (6,16.50) to calculate the slope:
x1 = 3, y1 = 8.25
x2 = 6, y2 = 16.50
slope = (16.50 - 8.25) / (6 - 3)
slope = 8.25 / 3
slope ≈ 2.75
Therefore, the rate of change in the purchase price is approximately $2.75 per pound.
