Equation of the parabola.
x² = - 6y.
As we know that,
Equation of parabola : x² = - 4ay.
Comparing both the equation, we get.
⇒ - 4a = - 6.
⇒ 4a = 6.
⇒ a = 6/4.
⇒ a = 3/2.
Vertex of parabola = (0,0).
Directrix of parabola = y = a ⇒ y = 3/2.
Axis of the parabola = x = 0.
Focus of the parabola = (0,-a) ⇒ (0,-3/2).

Equation of normal.
(1) = Point form : The equation to the normal at the point (x₁, y₁) of the parabola y² = 4ax is given by : (y - y₁) = -y₁/2a (x - x₁).
(2) = Parametric form : The equation to the normal at the point (at², 2at) is : y + tx = 2at + at³
.
(3) = Slope form : Equation of normal in terms of slope m is : y = mx - 2am - am³.
(4) = The foot of the normal is = (am², -2am).
