I can't figure out y=mx+b I think I forgot how to solve this. x+3y=6 then I have to put it back and shade one side of the graph.
\n" ); document.write( "-----------------------------
\n" ); document.write( "If you are shading, you have an inequality.
\n" ); document.write( "----
\n" ); document.write( "Let's assume you have x+3y < 6.
\n" ); document.write( "----
\n" ); document.write( "Then y < (-x/3) + 2
\n" ); document.write( "-------
\n" ); document.write( "Notice: No inequality is graphed directly.
\n" ); document.write( "You 1st must graph the boundary, which is
\n" ); document.write( "always an equality.
\n" ); document.write( "So, for your problem you should graph
\n" ); document.write( "y EQUALS (-x/3)+2 as a dashed line; dashed
\n" ); document.write( "because that boundary is not part of the
\n" ); document.write( "solution.
\n" ); document.write( "---
\n" ); document.write( "Then, since you want y LESS than (-x/3)+2
\n" ); document.write( "you should shade the half plane BELOW
\n" ); document.write( "the boundary to get:
