Question 62220
1st; 2x - 3y = 12
2nd: 3y - 2x = -12 
------------------
1st: Let x=0 then y=-4 giving pt. (0,-4)
Let y=0 then x=6 giving pt. (6,0)
--------------
2nd: Let x=0 then y=-4 giving pt. (0.-4)
Let y=0 then x=6 giving pt. (6,0)
------------
Plot these points and you will see that the
two equations are really the same.  The graph
is the line thru the pts. (0,-4), (6,0)
----------
{{{graph(300,200,-10,10,-10,10,(2/3)x-4)}}}
