Answer:
The unit rate = 27 miles per gallon.
Hence, option C is true.
Step-by-step explanation:
From the given line graph:
Taking two points
The unit rate can be determined by finding the rate of change or slope between the points (2, 54) and (6, 162)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(2,\:54\right),\:\left(x_2,\:y_2\right)=\left(6,\:162\right)[/tex]
[tex]m=\frac{162-54}{6-2}[/tex]
Refine
[tex]m=27[/tex]
Therefore, the unit rate = 27 miles per gallon.
Hence, option C is true.
