Algebra.Com's Answer #58241 by stanbon(75887) ![]() You can put this solution on YOUR website! Can you graph the inequality. \n" ); document.write( "y≥1-3x\r \n" ); document.write( "\n" ); document.write( "------------ \n" ); document.write( "You have to graph the boundary: y=1-3x \n" ); document.write( "Plot two points: \n" ); document.write( "(If x=0, y=1; If x=1,y=-2) \n" ); document.write( "Plot those points and draw a line thru them. \n" ); document.write( "That takes care of the EQUALITY. \n" ); document.write( "-------- \n" ); document.write( "To graph the INEQUALITY pick a test point like (0,0) \n" ); document.write( "Substitute those values into the inequality: \n" ); document.write( "0>1-3*0 \n" ); document.write( "0>1 \n" ); document.write( "That is wrong so that side of the boundary is NOT the solution \n" ); document.write( "set of the INEQUALITY; tho other side is so darken the other side. \n" ); document.write( "-------- \n" ); document.write( "The line and the darkened side (half-plane) is the graph you want. \n" ); document.write( "=========== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
