I'm just curious. Why not compute it yourself? Put the points in. See if they work.

Ok. (0,0) doesn't work. You can tell that immediately. To check if a point \((x_1,y_2)\) works, just put it in like this: \(2x_1+y_1<4\) and \(x_1y_1>3\). Here's an example: To test \((8,9)\) we do this: \[ \begin{align} 2(8)+(9)&<4\\ 16+9&<4\\ 25&<4 \end{align} \] Since \(25\) is not less than \(4\), the point \((8,9)\) does not work. Try the other points just like this. If they work for one inequality, check the other. If they work for both, then that's the point you pick. :D
