I'll do example for you - then you do the rest.

The first empty box (bottom-left) - you need to fill in the value of "y" using the function when you are given x = -8

y + 3 = -(1/2) * (x + 4)

y + 3 = -(1/2) * (-8 + 4)

y + 3 = -(1/2) * (- 4)

y + 3 = (4/2)

y + 3 = 2

y + 3 - 3 = 2 - 3

y = -1

Now you calculate the rest. If you get stuck - write back including your work and point out exactly where you are stuck!
