Detailed Solution

$P = ({at}^{2}, 2 at), slope o f \tan g e n t a t P = \frac{1}{t}$

Clearly Statement 1 is true

Statement - 2: $Given parabola y^{2} = 4 a x d i f f w . r . t o x o n b o t h s i d e s$

$\Rightarrow 2 y \frac{dy}{dx} = 4 a \Rightarrow 2 y \frac{dy}{dx} = \frac{y^{2}}{x} \Rightarrow \frac{dy}{dx} = \frac{y}{dx}$

Degree 1, order 1
