At one point on the trip the miles are recorded as 15,121 when the gas tank is 75% full. Use a ratio equation to determine the miles per gallon the sedan averages.

1090miles/gallon approximately

Step-by-step explanation:

On average a Sedan tank can hold 18.5 gallons.

If it's 75% full, it means it is 18.5 x 0.75 = 13.875 gallons full.

Since the number of miles covered was recorded as 15121 with 75% full gas tank, then to determine mile/gallon can be found by

15121/13.875 ≈ 1090miles/gallon

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
