Answer:
Circumcenter of triangle ![(4,-1)](https://tex.z-dn.net/?f=%284%2C-1%29)
Step-by-step explanation:
Given coordinates are ![(1,1)(1,-3)(7,-3)](https://tex.z-dn.net/?f=%281%2C1%29%281%2C-3%29%287%2C-3%29)
We will draw these points on the graph.
Let
,
and ![C(7,-3)](https://tex.z-dn.net/?f=C%287%2C-3%29)
We can see it is a right-angle triangle.
Let
be the midpoint of line ![AC](https://tex.z-dn.net/?f=AC)
So, the coordinate of the point
will be
![A(1,1)\ C(7,-3)\\\\Midpoint\ O\ will\ be\\\\O=(\frac{1+7}{2},\frac{1+(-3)}{2})\\ \\O=(\frac{8}{2},\frac{-2}{2})\\\\O=(4,-1)](https://tex.z-dn.net/?f=A%281%2C1%29%5C%20C%287%2C-3%29%5C%5C%5C%5CMidpoint%5C%20O%5C%20will%5C%20be%5C%5C%5C%5CO%3D%28%5Cfrac%7B1%2B7%7D%7B2%7D%2C%5Cfrac%7B1%2B%28-3%29%7D%7B2%7D%29%5C%5C%20%5C%5CO%3D%28%5Cfrac%7B8%7D%7B2%7D%2C%5Cfrac%7B-2%7D%7B2%7D%29%5C%5C%5C%5CO%3D%284%2C-1%29)
Also, we know the coordinates of circumcenter of a right angle triangle will be midpoint of its hypotenuse.
So, coordinates of circumcenter is ![(4,-1)](https://tex.z-dn.net/?f=%284%2C-1%29)
