7 The curve \(C\) has equation
$$y = \lambda x + \frac { x } { x - 2 }$$
where \(\lambda\) is a non-zero constant. Find the equations of the asymptotes of \(C\).
Show that \(C\) has no turning points if \(\lambda < 0\).
Sketch \(C\) in the case \(\lambda = - 1\), stating the coordinates of the intersections with the axes.
