I got the same as you. I checked their answer, and the point (-1,7) is on the circle. However if z=-1+7i then w is not "totally" imaginary. Really don't like it how they used that word lol, almost like they are being sarcastic, and they may as well be. So their answer is incorrect.
4. Thanks for telling.
