Answer 1

Step 1: Find the center.

Answer 2

is h,k 1,1 i have the an answer i just want to make sure its right
(x+1)^2+(y-1)^2=-2

Answer 3

Looks right to me

Answer 4

(x+1)^2+(y-1)^2=-2 <-- if you meant this as an example for the equation of a circle, yes is right

if you meant that as the actual Circle equation for this specific... well.... is not
you can find the center by getting the Midpoint of both points though
