Yeah that is correct. 3/4 is equal to .75
What is the rest of the problem? I can help you!
Answer: disagree its backwards
Step-by-step explanation: the x intercept always comes first so its actually (-4,2)
We know that the Circumcenter is the intersection of a triangle's right (perpendicular) bisectors. Once you have found two of these you can determine their point of intersection.
It is a proven mathematical concept that the third perpendicular bisector will also cross through this intersection point. While it is not necessary to construct all three it is often done so to verify that the intersection of the first two perpendicular bisectors was in fact correct.
