Use the substitution method to solve the system of equations. y = - 4x 8x - y = 6 A. (2, - 8) B. (1, - 4) C. 1/2-4 D. 1/2-2

Answer: D. (1/2,-2)

y = - 4x and 8x-y=6

what you do is switch the negative y to the other side and move the positive 6 to the other side thus making y=8x-6.

I don't get what those numbers are on the question but the way you solve it is by combining them and putting one y into the other

8x-6=-4x 12x=6 6/12=x. 5=x

then you plug in x to find y in whichever equation:

-4x=y - 4 (.5) = y - 2=y

so the final answer would be (.5,-2)
