    You want to keep track of the change between each set of numbers. For example, the first x is -3 and the second is 3. The change there is +6. The corresponding f(x) change is -40.

    And then from x2 to x3, the change is +4, while from y2 to y3 it is -10. Overall, how much did x change in total from x1 to x3? And how about for y1 to y3?

    The second and third x values respectively. x2 is 3 and x3 is 7.

    Be careful, slope is change in y over change in x. Rise/run is how you might remember it as. And f(x) is the rise.

    And also, they want the average. That means simplify it
