Question

Y=1/2x-6

X=-4
What is the solution to the system of equations
A. (-8,-4)
B.(-4,-8)
C.(-4,4)
D.(4,-4)

Answer 1

B. (-4, -8)

Explanation:

Put -4 into the first equation where x is, then evaluate. You will find ...

y = (1/2)(-4) -6 = -2 -6 = -8

Then the point that satisfies both equations is ...

(x, y) = (-4, -8) . . . . matches choice B

___

You can eliminate choices A and D, because they don't have -4 for the x-value.
