Question

Using the formula m= f(x2) - f(x1)/x2 - x1, what is the rate of change for the linear function that contains the

points (-3, 2) and (1,10)?

1/2

8

-4

2

Answer 1

2

Explanation:

The slope of the line through (-3, 2) and (1,10) can be found by lining up the point's vertically and subtracting then putting 2nd difference on top of first.

(1,10)

Minus

(-3,2)

-------

8/4=2

The slope is 2.
