-13-5=-18

Answer:

4) -18

8) I am not sure what you want answered for this question. Do you want slope?

Step-by-step explanation:

4) You have the equation: 2x+5

Plug in the first value of x = -9 to get f(-9) or the y/f(x)

2(-9)+5 = -13 = f(-9)

Plug in the second value of x =0 to get f(0) or the y/f(x) of that number

2(0) +5 = 5 = f(0)

Plug into f(-9)-f(0)

-13-5 = -18
