Start with
y%2Bx=3

y=3-x Solve for y

Now graph the equation y=3-x
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+3-x%29+
Now pick a test point (0,0) and evaluate it with y%2Bx%3E3

0%2B0%3E3 Plug in x=0, y=0
0%3E3 Since this isn't true, we don't shade the region containing (0,0). So we shade everything above the graph.
