Answer:

1)

3x + 7 = 13

3x = 13 - 7 = 6

x = 6/3 = 2

x = 2

2)

8 - 2b = -2

-2b = -2 - 8 = -10

b = -10/-2 = 5

b = 5

3)

5 + 4g + 8 = 1

4g = 1 - 5 - 8 = -12

g = -12/4 = -3

5)

Y = 6x - 15

(8,33) (-1,-21) (5,15)

6)

Y = -4x + 9

(-5, 29) (2, 1) (4, -7)

7)

Y = 2x - 1

(-4, -9) (0, -1) (7, 13)

8)

Y = -x + 9

(-9, 0) (1, 8) (5, 4)
