A line has equation \(y = 3kx - 2k\) and a curve has equation \(y = x^2 - kx + 2\), where \(k\) is a constant.
(i) Find the set of values of \(k\) for which the line and curve meet at two distinct points.
(ii) For each of two particular values of \(k\), the line is a tangent to the curve. Show that these two tangents meet on the x-axis.
