A curve has equation $y = k{x^2} + 1$ and a line has equation $y = kx$, where $k$ is a non-zero constant.
a) Find the set of values of $k$ for which the curve and the line have no common points.
b) State the value of $k$ for which the line is a tangent to the curve and, for this case, find the coordinates of the point where the line touches the curve.
