A graph of the cost of gas purchased depending on the number of gallons pumped has the points (4,15) and (8,30) . What is the rate of change in the cost of the gas as each gallon is pumped?(1 point)%0D%0A$ per gallon

To find the rate of change in the cost of gas per gallon, we need to find the slope of the line passing through the two given points.

The slope, or rate of change, is found using the formula:
slope = (change in y)/(change in x)

In this case, the change in y is the change in cost of gas, and the change in x is the change in the number of gallons pumped.

Using the points (4,15) and (8,30), we can calculate the slope:
slope = (30-15)/(8-4)
= 15/4

Therefore, the rate of change in the cost of the gas as each gallon is pumped is 15/4 dollars per gallon.
wrong lol.
Apologies for the mistake.

Therefore, the rate of change in the cost of the gas as each gallon is pumped is $3.75 per gallon.
