Y=-3x+4 is the correct answer
Answer:
y = -3x + 4
Step-by-step explanation: Substitute the numbers in for x & y to see which one is the answer.
(-1, 7):
y = -3x + 4
7 = -3(-1) + 4
7 = 3 + 4
7 = 7
TRUE
y = 2x - 9
7 = 2(-1) - 9
7 = -2 - 9
7 = -11
FALSE
y = 5x - 2
7 = 5(-1) - 2
7 = -5 - 2
7 = -10
FALSE
y = -3x + 7
7 = -3(-1) + 7
7 = 3 + 7
7 = 10
FALSE
Hope this helps you!!! :)
