EQUATIONS
===============================================================
[tex]\begin{cases}x+y\textless -4 \\ 3x+2y\textless-5 \end{cases}[/tex]
[tex]3+(-7)\textless-4\\3-7\textless-4\\-4\textless-4[/tex]
[tex]3(3)+2(-7) < -5\\9-14 < -5\\-5\textless-5[/tex]
since we plugged in the co-ordinates and got true statements in both equations , (3,-7) is a solution for the first one.
remember a point needs to make BOTH equations true
