Answer: C) y = -5x + 27 and D) y = 2x - 15
<u>Step-by-step explanation:</u>
Substitute x = 6 and y = -3 into each of the given equations to see which result in a TRUE statement.
A) y = -3x + 6
-3 = -3(6) + 6
-3 = -18 + 6
-3 = -12 FALSE
B) y = 2x - 9
-3 = 2(6) - 9
-3 = 12 - 9
-3 = 3 FALSE
C) y = -5x + 27
-3 = -5(6) + 27
-3 = -30 + 27
-3 = -3 TRUE!
D) y = 2x - 15
-3 = 2(6) - 15
-3 = 12 - 15
-3 = -3 TRUE!
E) y = -4x + 27
-3 = -4(6) + 27
-3 = -24 + 27
-3 = 3 FALSE
