Which ordered pair is a solution to y = 3+x? a) (-4,-1) b) (2,-1) c) (2,-5)

a

Step-by-step explanation:

If you substitue it in for a, you get 3-1=-4, which satisfies the equation.

The answer is A) (-4,-1)

Step-by-step explanation:

You have to substitute!!! :)

A) (-4,-1):

y = 3 + x

-1 = 3 + -4

-1 = -1

YES

B) (2,-1):

y = 3 + x

-1 = 3 + 2

-1 = 5

 NO

C) (2,-5):

y = 3 + x

-5 = 3 + 2

-5 = 5

  NO
