Answer by elima(1433) (Show Source): You can put this solution on YOUR website!
x-2y=4.
You need to put this in slope-intercept form;
y=mx+b
b = y-intercept
So lets begin;
x-2y=4
first subtract x from both sides;
-2y=-x+4
now divide each side by -2;
=
y=x-2
Now it is in slope-intercept form, what is the y-intercept? Remember b;
y-intercept = -2
