Plug in the values for x and y in the equation and see if they satisfy it:
(-2,16): y = -4(-2)^2 = -16, incorrect
(1,-8): y = -4(1)^2 = -4, incorrect
(0,-4): y = -4(0)^2 = 0, incorrect
(2,-16): y = -4(2)^2 = -16, correct
Therefore, the only solution pair is (2,-16).
Which of the following order pairs is a solution to the equation y = -4x ^ 2?
(-2,16)
(1,-8)
(0,-4)
(2,-16)
