Answer 1

Answer:

see explanation

Step-by-step explanation:

(1)

to calculate the slope m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 5) and (x₂, y₂ ) = (18, - 5)

m = $\frac{-5+5}{18+2}$ = $\frac{0}{20}$ = 0

(2)

divide number of miles travelled by number of gallons used

= $\frac{132}{6}$ = 22 miles per gallon

Answer 2

The one on the right is 22.
$132 \div 6$
which gives u a price of 22 per gallon
