X + 7 = - 3
x = - 3 - 7
x = - 10

Now put the value of x in 2nd equation,
- 10 - y = -3
- y = - 3 + 10
- y = 7
y = - 7

Answer:

1. Below 2. B. d = 8h

Step-by-step explanation:

The graph is a bit confusing. But basically, substitute x for the numbers they give you.

5 · 1 = 5 = y

5 · 2 = 10 = y

5 · 3 = 15 = y

5 · 4 = 20 = y

7 · 1 = 7 = y

7 · 2 = 14 = y

7 · 3 = 21 = y

7 · 4 = 28 = y
