Algebra.Com's Answer #60642 by sofiyacherni(99)![]() ![]() ![]() You can put this solution on YOUR website! ok \n" ); document.write( "2x-y>4 \n" ); document.write( "2x-4>y \n" ); document.write( "so y<2x-4 \n" ); document.write( "to graph this pick a few points, the easiest is to pick x=0 and x=1 \n" ); document.write( "so if x=0, plug it in the equation, then y=-4 \n" ); document.write( "and if x=1 then y=-2 now graph this on the plane \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "so since y is less than that then your solution lies below that line, not including the line, so part of quadrants I, III, and IV \n" ); document.write( " |
