- A 3
- B 4
- C 2
- D 1
Answer & Solution
Correct Answer
(B) 4
Step-by-step Solution
Detailed explanation
Let \(\left(x_1, y_1\right)\) and \(\left(x_2, y_2\right)\) be end point of diameter of circle, then equation of circle be \[ \left(x-x_1\right)\left(x-x_2\right)+\left(y-y_1\right)\left(y-y_2\right)=0 \] Given, equation of circle is…
