First graph the feasible region.

\n" ); document.write( "\n" ); document.write( "The feasible region is simplified to \"x%3C=2\" and \"0%3C=y%3C=5\" and the line \"x-y%3C=4\" does not contribute any constraint.
\n" ); document.write( "Since there is no minimum value for \"x\", there is no minimum value for \"p\".
\n" ); document.write( "The maximum value occurs at one of the two vertices.
