In order to find the rate at which truck consumes fuel, calculate the slope of the given graph, by using the following formula:


m=(y_2-y_1)/(x_2-x_1)

where (x1,y1) and (x2,y2) are two points on the line.

Based on the given graph, you can select the points:

(x1,y1) = (0,500)

(x2,y2) = (500,200)

By replacing the previous values into the expression for m and simplifying you get:


m=(200-500)/(500-0)=-(300)/(500)=-0.6

The previous result means that the truck consumes its fuel at a rate of 0.6 liters/kilometer
