If the focus of the parabola is (2,2), and the Quasilinear equation is x + Y-1 = 0, the parabola equation is solved

If the focus of the parabola is (2,2), and the Quasilinear equation is x + Y-1 = 0, the parabola equation is solved

The vertex of a vertical line passing through the focus is at the midpoint of the vertical line
Because the coordinates of the perpendicular foot are (- 1, - 1), and the coordinates of the focus are (1,1)
So the coordinates of the vertex are (1 / 2,1 / 2)
