Answer:
(2, 18) and (-3, -7)
Explanation:
y = 5x + 8 Substitute the value for y into the second equation
-10x + 2y = 16
-10x + 2(5x + 8) = 16
-10x + 10x +16 = 16
16 = 16 True
These two equation are the same line. So pick one of the equation to check which ordered pairs are true solutions.
Using y = 5x + 8
(0, -6) -5 = 5(0) + 8 ; -6 = 8 No
(-1, 9) 9 = 5(-1) + 8; 9 = -5 + 8 ; 9 = 3 No
(2, 18) 18 = 5(2) + 8; 18 = 10 + 8 = 18; 18 = 18 Yes
( -3, -7) -7 = 5(-3) + 8; -7 = -15 + 8; -7 = -7 Yes
