## Question

### Solution

Correct option is The equation of the axis of the ellipse is Solving this equation with x – y + 3 = 0, we obtain that the coordinates of z are Since A and A’ divide SZ internally and externally respectively in the ration e : 1 i.e. 1 : 2. So, their coordinates are  As C is the mid point of AA’. So, its coordinates are .
