What is the rate of change of the linear function that has a graph that passes through (9,2) and (3,-1)?

Your teacher wants you to find the slope

m = slope

m = (y2-y1)/(x2-x1)

m = (-1-2)/(3-9)

m = -3/(-6)

m = 1/2

Extra info:

We can think of the slope as

slope = rise/run

and furthermore,

Essentially we subtract the corresponding y coordinates together, subtract the x together (in the same order as the y values), then divide the differences.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
