For each ordered pair, substitute the values of x and y into the equation and see if it is a true statement.
A. y = -4x - 9 becomes 27 = (-4)(-9) - 9, which is true. Therefore, (–9, 27) is not the answer.
B. y = -4x - 9 becomes -21 = (-4)(3) - 9, which is true. Therefore, (3, –21) is not the answer.
C. y = -4x - 9 becomes 15 = (-4)(-6) - 9, which is true. Therefore, (–6, 15) is not the answer.
D. y = -4x - 9 becomes -28 = (-4)(5) - 9, which is false. Therefore, the answer is (5, -28).
Which ordered pair is not a solution of y = –4x – 9 ?
A. (–9, 27)
B. (3, –21)
C. (–6, 15)
D. (5, –28)
