JEE Main 2022 Mathematics question
Let a circle C touch the lines : and : , , ℝ. If a line passing through the centre of the circle C intersects at (−1, 2) and at (3, −6), then the equation of the circle C is :
Answer: (3)
Solution
The centre is the midpoint of the two points: ((3 − 1)/2, (−6 + 2)/2) = (1, −2). passes through (−1, 2): −4 − , so passes through (3, −6): $12 +
