Answer:

(4, -4)

Step-by-step explanation:

By plugging in the 4 and -4 for x and y respectively, you come up with a true statement, which means it is the correct answer choice.

-5(4) - 4(-4) = -4

-20 + 16 = -4 .     (remember multiplying two negatives = a positive)

25(4) + 20(-4)

100 + (-80) = 20
