One of the Important Factors Determining a Car's Fuel Efficiency $\frac { 1 } { \sqrt { y } }$

One of the important factors determining a car's fuel efficiency is its weight.This relationship is examined for 11 cars,and the association is shown in the scatterplot below. What re-expression of Y might be appropriate?

A) log y gallons per mile
B) 100 ? $\frac { 1 } { \sqrt { y } }$ gallons per 100 miles
C) -100 ? $\frac { 1 } { y }$ gallons per 100 miles
D) 100 ? $\frac { 1 } { y }$ gallons per 100 miles
E) 100 ? $\sqrt { y }$ gallons per 100 miles
