Statement I: If m₁,m₂ are the slopes of the tangents drawn from an external point $\mathrm{P}\left({\mathrm{x}}_1,{\mathrm{y}}_1\right)$ to the parabola ${\mathrm{y}}^2=4\mathrm{ax}$ then ${\mathrm{m}}_1+{\mathrm{m}}_2=\frac{{\mathrm{y}}_1}{{\mathrm{x}}_1},{\mathrm{m}}_1{\mathrm{m}}_2=\frac{\mathrm{a}}{{\mathrm{x}}_1}$.
Statement II: Equation of the tangent having slope m to the parabola ${\mathrm{y}}^2=4\mathrm{ax}$ is $\mathrm{y}=\mathrm{mx}+\frac{\mathrm{a}}{\mathrm{m}}$.
