Question 510512
There is no real question here, but this equation plots as a straight line.  If you want to see it, get some graph paper.  Here are some easy to plot points (x,y) that when plotted and connected, will show you what the line looks like.  Note, this line would go to infinity in both directions because in this problem we have nothing to bound our solution:
...
(x, y)
--------
(12, -26)
(-8, -15)
(-4, -4)
(0, 7)
(4, 18)
(8, 29)
(12, 40)
...
cheers,
