Answer 1

see explanation

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 =
`(-5+5)/(18+2)` =
`(0)/(20)` = 0

(2)

divide number of miles travelled by number of gallons used

=
`(132)/(6)` = 22 miles per gallon

Answer 2

the one on the right is 22.

`132 / 6`
which gives u a price of 22 per gallon
