You can put this solution on YOUR website!
Rewrite for y (is easiest):
y < x/2 +3
So, draw the function f(x)=x/2 +3
graph%28+200%2C+200%2C+-10%2C+10%2C+-10%2C+10%2C+x%2F2%2B3+%29
Now, we want y to always be less than that line (the line itself will be dotted!). So, we shade below it as pictured (fairly poorly but it is better than nothing):
graph%28+400%2C+400%2C+-10%2C+10%2C+-10%2C+10%2C+x%2F2+%2B3%2C+y+%3C+x%2F2+%2B3+%29
