Question

The equation y=45x represents the number of miles, y, Mr. Miller’s car can travel using x gallons of gas. Which data display represents a car that gets more miles per gallon than Mr. Miller’s car?

Answer 1

You can use, for example, the following data:
 0 0
 1 60
 2 120
 3 180
 4 240
 5 300
 6 360
 7 420
 8 480
 9 540
 10 600
 This data represents a function of:
 y = 60x
 Which means that the car travels 60 miles per cad gallon.
 This distance traveled per gallon is greater than the distance traveled by Mr. Miller's car.
