parallel lines have the same slope
\n" ); document.write( ":
\n" ); document.write( "the x-intercept is (2, 0)
\n" ); document.write( ":
\n" ); document.write( "the equation for the line is
\n" ); document.write( ":
\n" ); document.write( "x = 2, all points on this line have the same x-coordinate
\n" ); document.write( ":
\n" ); document.write( "the gradient(slope) tends to infinity
\n" ); document.write( ":
