Question

Need help! Cannot understand Circumcenter of a triangle!
Hello! I've been stuck on a test for a while now mostly because of how hard the whole unit on triangles was! My teacher won't call me back, so I need some help. Here is my question:
"5. Find the circumcenter of triangle EFG, with E being (3,6), F being (3,4), and G being (7, 4)."
Possible answers: A. (5,5)
B. (3,6)
C. (4,6)
D. (6,4)
What I know so far:
Midpoint of EF: (3,5)
Midpoint of FG: (5,4)
Midpoint of GE: (5,5)
slope:
EF: none
FG: 0
GE: 2/4
The part I am stuck on is the last step of y-y1= m (x-x1) Please help!
