The system of circle passing through the intersections of the circle C and the line L can be given by This system of circles must pass through points P and Q. We like to find one of the circles in this system which passes through the point R (2,1).ranscript. Ex 7.4, 3 Find the centre of a circle passing through the points (6, – 6), (3, – 7) and (3, 3). Let the circle pass through points Points A (6, −6), B (3, −7) and C (3, 3) Let O(x, y) be the centre of the circle Since the centre is equidistant from all the Points Lying on the circle.
