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 calculate the slope of the line passing through the given points.
The slope of a line is given by the formula:
slope = (change in y-coordinates) / (change in x-coordinates)
In this case, the change in the y-coordinates is 16.50 - 8.25 = 8.25 and the change in the x-coordinates is 6 - 3 = 3.
So, the slope (rate of change) is 8.25/3 = 2.75 dollars per pound.
Therefore, the rate of change in the purchase price is $2.75 per pound.
