1. use the table and the graph to answer the questions.
function 1
x-1,-2,-3,2,3y 3,5,7,-3,-5
function 2 is a graph which is down below
(a) what is the rate of change (slope) for each function? show your work.
(b) which function has the greater rate of change (slope)?

The correct answer for this question is this one:

The first function has the points
x -1,-2,-3,2,3
y  3,5,7,-3,-5

From that, the slope we can get is 
m = (y1 - y2) / (x1 - x2)
m = (3 - 5) / (-1 - -2)
m = -2 / 1
m = -2

The second function, given a graph, it has a slope of (using rise / run technique):
m = -4 / 1
m = -4

The function that has the greater rate of change (slope) is the SECOND function.

The answer for this question is 80
