The focus of the parabola is at (0,0) and the directrix is the line x=2 thus the axis of the parabola is the x axis and the parabola is a parabola opening towards the left.
The vertex of the parabola is a point on the parabola and is hence equidistant from the directrix and the focus.
Also the vertex has to lie on the axis. Thus the vertex is a point lying on the x axis equidistant from both the origin and the directrix.
Thus the required point is (1,0)
