Plot the lines first.
\n" ); document.write( "Then choose a point in the region not on the line.
\n" ); document.write( "If the equation is true, that region should be shaded.
\n" ); document.write( "Else, the other region.
\n" ); document.write( "\"graph%28300%2C300%2C-10%2C10%2C-10%2C10%2C%28-12-x%29%2F4%29\"
\n" ); document.write( "Choose (0,0), it's convenient.
\n" ); document.write( "\"0%2B4%280%29%3E=-12\"
\n" ); document.write( "\"0%3E=-12\" True, shade the region containing (0,0).
\n" ); document.write( "\"graph%28300%2C300%2C-10%2C10%2C-10%2C10%2Cy%3E=%28-12-x%29%2F4%29\"

\n" ); document.write( "\"3%280%29-0%3E=1\"
\n" ); document.write( "\"0%3E=1\" False, shade the region that doesn't contain (0,0).
\n" ); document.write( "\"graph%28300%2C300%2C-5%2C5%2C-5%2C5%2Cy%3C=3x-1%29\"
