Answer:

Explanation:

The train uses


(400gallons)/(200miles)

If you reduce that you get that the train uses


(2gallons)/(1mile)

To find the slope of the line, we will use the 2 points on the coordinate plane where the graph goes through: (0, 0) and (400, 200)

Applying the slope formula:


m=(200-0)/(400-0)=(1)/(2)
