slope intercept form is y=mx+b
---------------------
2x-3y=9
-3y=-2x+9
y=2/3x-3
------------
6x+9y=27
9y=-6x+27
y=-6/9+3
y=-2/3x+3
---------------
x-4y=20
-4y=-x+20
y=1/4x-5
-------------
7x-3y=12
-3y=-7x+12
y=7/3x-4

I'll do the first two to get you started.
# 1
Start with the given equation.
Subtract from both sides.
Rearrange the terms.
Divide both sides by to isolate y.
Break up the fraction.
Reduce.
So the equation is now in slope intercept form where the slope is and the y-intercept is note: the y-intercept is the point )
