Solve -4x - 8y = 24 for y

Question

F) y = -1/2x - 3

G) y = -1/2x +3

H)y = 1/2x - 3

J)y = 1/2x + 3

Answer 1

The answer is (F)

You are being asked to rewrite the function/equation for y; put in the form of a STRAIGHT LINE y = mx + b

So...

-4x - 8y = 24

When you add 4x to both sides, it will cancel out on the LHS and go onto the RHS

-8y = 4x + 24

To isolate y, divide both sides by -8 so it cancels out on the LHS and factor it into EACH term on the RHS

y = (4x + 24)/ -8

y = -(1/2)x - 3 Final Answer
