Algebra.Com's Answer #473695 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! How do you graph these inequalities in the coordinate plane? These are linear inequalities in Two Variables. \n" ); document.write( "------ \n" ); document.write( "Procedure: You don't graph the inequality; you graph the boundary \n" ); document.write( "of the inequality. Then you determine the area corresponding to \n" ); document.write( "the inequality::: \n" ); document.write( "----------------- \n" ); document.write( "a.) -3x+5y>= 2 \n" ); document.write( "1st: Graph y = (3/5)x + (2/5) as a solid line \n" ); document.write( "2nd: Since you want y GREATER than (3/5)x + (2/5), shade the half-plane ABOVE the boundary. \n" ); document.write( " \n" ); document.write( "================================================================ \n" ); document.write( "b.) x-4y>-3 \n" ); document.write( "1st: Graph y = (1/4)x + (3/4) as a dashed line. \n" ); document.write( "2nd: Since you want y < (1/4)x+(3/4), shade the half-plane BELOW \n" ); document.write( "the boundary. \n" ); document.write( " \n" ); document.write( "================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
