$\"+y+=+-1+\"$ is a line through the point ( 0,-1 )
\n" ); document.write( "and is parallel to the x-axis
\n" ); document.write( "---------
\n" ); document.write( "Any line perpendicular to this line has to be
\n" ); document.write( "parallel to the y-axis, so it has an infinite slope
\n" ); document.write( "---------
\n" ); document.write( "Since it goes through (1,6), every point on this line
\n" ); document.write( "has the same x-coordinate, and looks like (1,y)
\n" ); document.write( "where $\"y\"$ can be any value.
\n" ); document.write( "---------
\n" ); document.write( "So $\"+x+=+1+\"$ describes this line \n" ); document.write( "

\n" );
