  Sketch and describe the following curves, showing clearly the coordinates of the centrea and asymptotes if any.

  x^2 - 2x - y^2 - 2y =1

  I found the centre to be (1, -1) and the asymptotes to be y = x-2 and y = -x-2. There seems to be sth wrong with one of the asynptotes equation before if I draw out the 2 asymptotes, they meet at (0, -2). Or is the asymptotes supposed to be y = 2-x?
