Question

What is the answer to 8x - 4y = 16

Answer 1

Answer:4.00000

Step-by-step explanation:

 Slope = 2

 x-intercept = -4/2 = -2

 y-intercept = 4/1 = 4.00000

Answer 2

Solve for y in terms of x, then plug it back into the equation. Once you isolate y you should get:
-4y = -8x + 16
y = 2x - 4

Plug this in for y into the original:
8x - 2(2x - 4) = 16
Solve for x to get x = 2
Solve for y now to get y = 0
