If \(P(-3,2)\) is an end point of the focal chord \(P Q\) of the parabola \(y^2+4 x+4 y=0\), then the slope of the normal drawn at \(Q\) is
- A \(\frac{-1}{2}\)
- B 2
- C \(\frac{1}{2}\)
- D -2
Answer & Solution
Correct Answer
(A) \(\frac{-1}{2}\)
Step-by-step Solution
Detailed explanation
\(P(-3,2)\) is an end point of focal chord \(P Q\) of the parabola \(y^2+4 x+4 y=0\) \((y+2)^2=-4(x-1)\) Let \(x-1=-t^2 y+2=-2 t \Rightarrow y=-2 t-2\)…
