Question

I need help with this

Answer 1

Answer: A

(2, -4) and (0,4);

x, y x, y

A. y = -4x +4; substitute the pairs

(2,-4)

-4 = -4(2) + 4 = -4; -4 = -4

(0,4)

4 = -4(0) + 4 = 4; 4 = 4

B. y = -4x - 4

(2, -4)

-4 = -4(2) - 4 = -12; -12 ≠ -4

(0,4)

4 = -4(0) - 4 = -4; -4 ≠ 4

C. y = 4x - 4

(2, -4)

-4 = 4(2) - 4 = 4; 4 ≠ -4

(0,4)

4 = 4(0) - 4 = -4; -4 ≠ 4

D. y = 4x + 4

(2, -4)

-4 = 4(2) + 4 = 12; 12 ≠ -4

(0,4)

4 = 4(0) + 4 = 4; 4 = 4

Answer A works out for both ordered pairs.
