Algebra.Com's Answer #58818 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Let's say you have y>=3 \n" ); document.write( "You always start by graphing the EQUALITY because that is \n" ); document.write( "the boudary of the INEQUALITY. \n" ); document.write( "So you graph y=3 \n" ); document.write( "------------- \n" ); document.write( "Then you do the following: \n" ); document.write( "1st: pick a test point, like (0,0) \n" ); document.write( "2nd: substitute that information into the INEQUALITY: 0>3 \n" ); document.write( "3rd: determine whether the result is trur or false: it is false \n" ); document.write( "4th: if it is false the half-plane on the OTHER side of the boundary \n" ); document.write( "from the test point is the solution area for the inequality. \n" ); document.write( "if it is true the half-plane that contains the test point is the \n" ); document.write( "solution area for the inequality. \n" ); document.write( "5th: darken the appropriate half-plane. \n" ); document.write( "=========== \n" ); document.write( "cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
