To graph these inequalities, the easiest thing is to first rewrite them so that on the left side, there is only y.
x + y < 3, x - y > 2
y < 3-x, y < x-2
Then, plot two functions: y=3-x, y=x-2: graph%28+300%2C+200%2C+-5%2C+5%2C+-5%2C+5%2C+3-x%2C+x-2%29+
because both equations say y < something, our solution is the area below both straight lines.
