caroline incorrectly answered the following problem:

which ordered pair would not appear as a solution for the linear equation y = -4x - 2?
a) (1, -6)
b) (-1, 5)
c) (-4, 14)
d) (2, -10)

caroline chose a as her answer. why is she incorrect?
a) (1, -6) is a solution because it creates a true statement when substituted into the equation
eliminate
b) (1, -6) is a solution because y = -6
c) (1, -6) is a solution because it creates a false statement when substituted into the equation
d) (1, -6) is a solution because it is near the y-intercept of -2.
