Question

Which of the following equations is the slope-intercept form of 4x - 2y = 8?
y = 2x - 4
y = -4x - 8
y = 1/2 x + 2
y = -2x + 4

Answer 1

Slope-intercept form: \(\Large y=mx+b\)

Answer 2

To do this all you have to do is isolate the y variable. Do this by subtracting 4x. You get
-2y = 8 - 4x. If you rearrange the right side, you get
-2y = -4x + 8. Now divide everything by -2 to isolate the y.
y = 2x-4.

ohhh thanks (: i get it now
