I would use the distance formula to solve this problem:
Distance formula:
(x1,y1) = (3,5)
(x2,y2)= (0,1)
Plug in points to find radius:
r=
r=
r=
r=
r=
r=
r= 5 units
To find the other point on the circle that crosses the y-axis change the sign of y2.
(x1,y1) = (3,5)
(x2,y2) = (0,-1)
Because they don't have the same answer
