All lines with undefined slopes are vertical lines of the form x = k\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "k in this case must be 9 in order for x = k to go through (9, -2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the answer is x = 9
\n" ); document.write( "
\n" );
