perpendicular to $\"x+=+-3\"$ , -> $\"x+=+-3\"$ is vertical line\r
\n" ); document.write( "\n" ); document.write( "horizontal line $\"y=a\"$ is perpendicular to vertical line \r
\n" ); document.write( "\n" ); document.write( "since passes through ( $\"8\"$ , $\"+7\"$ ), horizontal line is $\"y=7\"$ \r
\n" ); document.write( "\n" ); document.write( "
