Answer:


y = (1)/(2)x -2

Explanation:

Pre-Solving

We are given the following equation:
2x - 4y = 8

We want to write this equation in slope-intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y-intercept.

Solving

As we can see, in slope-intercept form, the value of y is isolated by itself on one side.

So, we should solve the equation for y.

First, subtract 2x from both sides.

2x - 4y = 8

-2x -2x

__________________

-4y = -2x + 8

Divide both sides by -4.


y = (1)/(2)x -2
