- A (-2 , 3)
- B (3 ,-2 )
- C (3 ,2 )
- D (2, 3)
Answer & Solution
Correct Answer
(D) (2, 3)
Step-by-step Solution
Detailed explanation
The all conjugate lines of the line \(5 x+7 y-78=0\) with respect to circle \(x^2+y^2+6 x+8 y-96=0\) passes through the pole of the given line with respect to given circle. Let required pole is \(P\left(x_1, y_1\right)\), so equation of polar of point…
