Question

I have been doing math all day, please help!

Answer 1

y=-3x+4 is the correct answer

Answer 2

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!!! :)
