Respuesta :
(Could easily be wrong, Math is not my strongsuit) I think its D, because you are suppose to convert the fuel tank capacity to the miles per gallon.
28 mi/gallon
In the beginning Sully has 16 gallons of fuel, and can drive
16 gallons*28 mi/gallons=448 mi
At the x=0, y=448 mi - this is y-intercept
28 mi/h is a slope ( for one h - 28 mi, for 2 h - 28*2 and so on)
The function is y=448-28x.
Answer is C.
