Find the slope of the line containing the pair of points.
(-9,- 8) and (-8,-6)

which is just 2

Step-by-step explanation:

slope =

So plug the numbers in, now it should look like

-6 - (-8) = 2

-8 - (-9) = 1

So the slope is

a .4y4

hope this !

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
