You can put this solution on YOUR website!
Every point on the line

has an x-coordinate of -8. So if you calculate the slope, using:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

,\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the denominator is zero regardless of what two points on the line you select for

. Therefore the slope is undefined. This is a vertical line.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
