Everything is correct except it should be -13 in the line equation. Good job!
Hi,if my calculations are correct then the inversion point is (129/65,47/65)
Sorry,I won't be able to work on it for the next 9 hours,But i'll let you know what i get.
How far did you make it with the problem?
I almost forgot about this problem,i'll try now
Have you tried first finding the inverse of the point with respect to the circle?
Given a circle (x-1)^2+(y+1)^2=16 and a point (5,6),what will be the reciprocation line of this point?
