Thank you for your response! Actually The point P could be anywhere on the arch that is being formed by the circle, so the line doesn't intersects the centre of the circle. I see now where I got it wrong, should have substituted y instead of b. Thanks!

1. I basically have to find the coordinates of P. All the pink lines are know, coordinates of points A and centre of circle are know. 2. (x-a)^2 + (y-b)^2 = r^2 [b]3. I try to substitute mx+c into the equation and get (x-a)^2 + (y-mx-c)^2 + r^2= 0 but I can't work out what m and...
