Which ordered pairs are solutions to the equation? Select all that apply.
(0, 4)
(0, -4)
(-1, -7)
(7, -1)
(2, 2)
(3, 5)

Answer

Solutions:

  1. (0, -4): Substitute x = 0 into 3x = y + 4, we get 0 = y + 4, so y = -4.
  2. (3, 5): Substitute x = 3 into 3x = y + 4, we get 9 = y + 4, so y = 5.

Not Solutions:

  1. (0, 4): Substitute x = 0 into 3x = y + 4, we get 0 = y + 4, so y = -4, not 4.
  2. (-1, -7): Substitute x = -1 into 3x = y + 4, we get -3 = y + 4, so y = -7.
  3. (7, -1): Substitute x = 7 into 3x = y + 4, we get 21 = y + 4, so y = 17, not -1.
  4. (2, 2): Substitute x = 2 into 3x = y + 4, we get 6 = y + 4, so y = 2.
