[ x + 2y ]greater than or equal to 6
\n" ); document.write( "------------
\n" ); document.write( "This means:
\n" ); document.write( "x+2y>=6 OR x+2y<=-6
\n" ); document.write( "y>=(-1/2)x+3 OR y<=(-1/2)x-3
\n" ); document.write( "----------------------
\n" ); document.write( "Graph the two lines:
\n" ); document.write( "y>=(-1/2)x+3
\n" ); document.write( "Two points are (0,3) and (2,2)
\n" ); document.write( "Draw the line and shade the half-plane above the line.
\n" ); document.write( "y<=(-1/2)x-3
\n" ); document.write( "Two points are (0,-3) and (2,-4)
\n" ); document.write( "Draw the line and shade the half-plane below the line.
\n" ); document.write( "---------
\n" ); document.write( "The final graph is the union of the lines and the shaded areas.
