The line graph shows the miles per gallon for a car.

what is the unit rate of gas usage for the car?

35 miles per gallon is the unit rate of gas usage for the car.

Step-by-step explanation:

Slope of the line will give the unit rate of gas usage for the car:

Slope m for points :

We have :

: (2,70) (3,105)

Slope of the lin e:

35 miles per gallon is the unit rate of gas usage for the car.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
