Answer:
(x-0)^2-(y+1)^2=153
Step-by-step explanation:
Find midpoint by averaging x-value and y-values
Midpoint: (0, -1)
Find radius by calculating distance from center to a point on the diameter.
Radius: 12.369
Use circle formula: (x-h)^2+(y-k)^2=r^2
Hint: (h,k) is the center
Answer: (x-0)^2-(y+1)^2=153
