Answer: (2,4)
Step-by-step explanation:
For us to solve this, we put the value of x and y and check if it's equal to -4.
a. (4,4)
4x - 3y = -4
= 4(4) -3(4)
= 16 - 12
= 4
b. (2,4)
4x - 3y = -4
= 4(2) -3(4)
= 8 - 12
= -4
c. (2,-4)
4x - 3y = -4
= 4(2) -3(-4)
= 8 + 12
= 20
d. (4,-4)
4x - 3y = -4
= 4(4) -3(-4)
= 16 + 12
= 28
Therefore, the answer is (2,4)
