Think about a vertical line as having the same
\n" ); document.write( "x-coordinate no matter what y is
\n" ); document.write( "So, the equation for a vertical line through
\n" ); document.write( "(5,3) is \"x+=+5\"
\n" ); document.write( "-----------
\n" ); document.write( "Just look at the x part of the point (x,y)
\n" ); document.write( "If it's not \"5\", it's not on the line
\n" ); document.write( "
\n" );
