Question

Write the equation 4x-2y=8 in slope intercept form?

Answer 1

Simple....

you have: 4x-2y=8

You want to re-write the equation in slope-intercept form..or y=mx+b

4x-2y=8

Isolate y....

4x-2y=8
-4x     -4x

-2y=-4x+8

Now divide...

$\frac{-2y}{-2} = \frac{-4x+8}{-2}$

y=2x-4

Thus, your answer.

Answer 2

slope intercept is y=mx+b
siolve for 1y

4x-2y=8
minus 4x both sides
-2y=-4x+8
divide both sides by -2
y=2x-4
