Question

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)y2-y1/x2-x1

Answer 1

you sure

Answer 2

Using the formula for rate of change, we have:

Rate of change = (y2 - y1)/(x2 - x1)

Substituting the given coordinates, we have:

Rate of change = (30 - 15)/(8 - 4)

Simplifying, we get:

Rate of change = 15/4

Therefore, the rate of change in the cost of gas as each gallon is pumped is 15/4.

Answer 3

Apologies for the mistake. Let's reevaluate the problem correctly.

The rate of change in the cost of gas as each gallon is pumped can be determined using the formula:

Rate of change = (change in y)/(change in x)

Given the points (4,15) and (8,30), the change in y (cost of gas) is 30 - 15 = 15, and the change in x (number of gallons) is 8 - 4 = 4.

Plugging these values into the formula, we get:

Rate of change = 15/4

Therefore, the rate of change in the cost of gas as each gallon is pumped is 15/4.
