Question
Find all points Q such that
(i) d(P,Q)= 5 when P= (3,-3),
(ii) the x-coordinate of Q = 6
(i) d(P,Q)= 5 when P= (3,-3),
(ii) the x-coordinate of Q = 6

I am wondering what the function d is.

Q would be the infinite set of points (x,y) such that
(x-3)^2 + (y+3)^2 = 25
ii) your second part makes no sense to me.
You wanted Q to be a set of points, thus Q=6 is meaningless
Did you mean, find x when y = 6 ???
(x-3)^2 + (y+3)^2 = 25
