how to graph these inequalities.
\n" ); document.write( "Such as: y\n" ); document.write( "-------------------------
\n" ); document.write( "You have to graph the boundary in order to graph an inequality.
\n" ); document.write( "Graph y = x+1 as a dashed line. It is the boundary
\n" ); document.write( "for y < x+1
\n" ); document.write( "Then shade the half-plane BELOW the boundary because you want
\n" ); document.write( "the graph of y BELOW x=1.
\n" ); document.write( "----
\n" ); document.write( " $\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2Cy%3Cx%2B1%29\"$
\n" ); document.write( "----
\n" ); document.write( "Graph 3x+4y >= 12
\n" ); document.write( "1st graph the boundary: y = (-3/4)x + 3
\n" ); document.write( "2nd shade the half-plane ABOVE the boundary.
\n" ); document.write( " $\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2Cy%3E%28-3%2F4%29x%2B3%29\"$
