Express the equation in intercept form $\"x%2Fa+%2B+y%2Fb+=+1\"$ \r
\n" ); document.write( "\n" ); document.write( "Divide both sides by -21:\r
\n" ); document.write( "\n" ); document.write( " $\"%283x%29%2F%28-21%29+%2B+%28-6y%29%2F%28-21%29+=+1\"$ \r
\n" ); document.write( "\n" ); document.write( "<==> $\"x%2F%28-7%29+%2B+%282y%29%2F7+=+1\"$
\n" ); document.write( "<==> $\"x%2F%28-7%29+%2B+y%2F%287%2F2%29+=+1\"$ \r
\n" ); document.write( "\n" ); document.write( "Therefore the x-intercept is (-7,0), and the y-intercept is (0,7/2). \n" ); document.write( "
