Julie’s family took a 4-day trip. Julie’s mother wrote an equation to calculate their gas mileage, m, in miles per gallon. Let d = the number of total miles driven on the trip. Let g = the total number of gallons of gas used for the trip. =

What was the gas mileage for the 4-day trip?

Step-by-step explanation:

Given

See attachment for missing details

Required

Determine the gas mileage for the trip

First, we calculate the miles driven

--- d

Next, we calculate the amount of gas used

---- g

The gas mileage is then calculated as:

Hence, the gas mileage is 26 miles per gallon

y - y1 = m(x- x1)

y - (-5) = 2/3(x -0)

y + 5 = 2/3x

y = 2/3x - 5
