Step-by-step explanation:

15y : 15 x 3 = 45

xy :  2 x 3 = 6

y + 23 : 23 + 3 = 26

5x + 9 : 5 x 2 = 10 + 9 = 19

6x - 2 : 6 x 2 = 12 - 4 = 8

yz : 3 x 4 = 12

y + 12 : 3 + 12 = 15

2z - 7 : 2 x 4 = 8 - 7 = 1

9x + y : 9 x 2 = 18 + 3 = 21

6x + 12 : 12 + 12 = 24

xz + 4 : 2 x 4 = 8 + 4 = 12

5x + 6z = 10 - 24 = -14

Step-by-step explanation:

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
