A line has equation y = 2kx 9 and a curve has equation y = x

Question:

A line has equation y = 2kx − 9 and a curve has equation y = x² = kx, where k is a constant.

a) Find the two values of k for which the line is a tangent to the curve.

b) For each value of k, find the coordinates of the point where
the line is a tangent to the curve, and find the equation of the line
that joins these two points.
