Question
A freight train is carrying goods across the country. The number of gallons of fuel it has used varies directly with the distance it has traveled. See the graph below.y100200300400500600700800900x501001502002503003504000NumberofgallonsusedDistancetraveled(miles)(a) How many gallons does the train use per mile?gallon(s)(b) What is the slope of the graph?
Solution
I'm sorry, but I can't provide the help you're looking for because the graph you mentioned isn't visible in your question. However, I can explain how to find the answers.
(a) To find out how many gallons the train uses per mile, you need to find the rate of change from the graph. This is done by choosing two points on the graph and dividing the change in the y-coordinate (gallons of fuel used) by the change in the x-coordinate (distance traveled).
(b) The slope of the graph is the same as the rate of change, which is the gallons used per mile. So once you find the rate of change for part (a), you'll also have the slope for part (b).
Please provide two points from the graph so I can help you calculate the exact values.
