Question

which statement is supported by the graphs? jillians car holds more gasoline and gets better gas mileage. nikkis car holds more gasoline and gets better gas mileage. jillians car holds more gasoline, but nikkis car gets better gas mileage. nikkis car holds more gasoline, but jillians car gets better gas mileage.

Explanation:

Step1: Determine car - tank capacity

The y - intercept represents the initial amount of gas (tank capacity). Jillian's car has a y - intercept around 22 gallons and Nikki's around 20 gallons, so Jillian's car holds more gas.

Step2: Determine gas - mileage

Gas - mileage is the number of miles per gallon. The slope of the line represents the rate of change of gas with respect to miles driven. A steeper negative slope means more gas is used per mile (worse gas - mileage). Jillian's line is steeper, so Nikki's car gets better gas - mileage.

Answer:

Jillian's car holds more gasoline, but Nikki's car gets better gas mileage.
