Well you know the distance formula right? Plug the values you know in
E.g. AC= 5
Which means-> (6-2)^2+ (-2-k)^2= 25
Ill leave you to do the rest.

Well i got 16+(k+2)^2=25, i expand the bracket right?

No; leave it and subtract 16 from both sides.
Take the square root and you'll have 2 possible values.
