equation is y=4
\n" ); document.write( "This line is parallel to x axis\r
\n" ); document.write( "\n" ); document.write( "a perpendicular line to this will be parallel to y axis.
\n" ); document.write( "(3,7) ----its x coordinate is 3
\n" ); document.write( "so the equation will be x=3
\n" ); document.write( "
