Question

Cory remembers that his ATV had 4 gallons of gasoline in the tank on Monday. After driving a total of 40 miles during

the week, he has 2 gallons of gas remaining. Find the slope of the graph representing this situation.

Answer 1

-1/20

Explanation:

For a graph like this you should make the gallons of gas on y-axis and the miles driven on the x-axis.

To find slope the formula is (y2-y1)/(x2-x1)

So in this case it is 2-4/40-0

-2/40

This reduces to -1/20
