Answer:
Let the Distance traveled by car = X miles
Then amount of gas consumed= Y gallons
As car travels more distance, amount of gas consumption will increase.
So,⇒Amount of gas Consumption=k× Distance traveled by car
Where k is sign of proportionality.
⇒Y = k X
This is equation in two variable of a line passing through the origin.
Drawn the Graph for you below
If X=1, Y=1
then k=1/1=1
If X=2, Y=2, then k=1
It shows uniform motion of car.
