Question

Which of the following equations is equivalent to x - y = 8? 2x - 4y = 8 2x - 4y = 64 4x - 2y = 64

Answer 1

Answer:

Say x = 12 and y = 4  

12 - 4 = 8

Number 1

2(12) - 4(4) = 8

24 - 16 = 8

Step-by-step explanation:

Answer 2

Answer:

The answer is is B. 2x -4y = 64

Step-by-step explanation:

Because both 1/4 x - 1/2 y = 8 and 2x - 4y = 64 have (x,y) intercepts the same.

x - (32,0)

y - (0,-16)

Plus, I just did it and got it right.
