Start with a general equation,
\n" ); document.write( " $\"Ax%2BBy=1\"$
\n" ); document.write( "Then use the points to solve for A and B.
\n" ); document.write( " $\"A%283%29%2BB%280%29=1\"$
\n" ); document.write( " $\"3A=1\"$
\n" ); document.write( " $\"A=1%2F3\"$
\n" ); document.write( "and
\n" ); document.write( " $\"A%280%29%2BB%28-9%29=1\"$
\n" ); document.write( " $\"-9B=1\"$
\n" ); document.write( " $\"B=-1%2F9\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"x%2F3-y%2F9=1\"$
\n" ); document.write( " $\"highlight%283x-y=9%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
