How many miles does the train travel per gallon?
What is the slope of the graph?
1. From the graph, one of the intersection points is: (50, 100), which means that to cover 50 miles, takes 100 gallons, or . 

   In other words, in travelling , 1 gallon of fuel is used.

2. From the graph, start at point (0, 0), or the origin. Move UP the y-axis to 50, and then RIGHT, to x = 100, or intersection point: (50, 100).

   This gives you
