To find the coordinates of the **circumcenter** of a triangle, we need to follow these steps:

1. **Identify the vertices of the triangle**:
   Based on the image, I’ll analyze and estimate the coordinates of the three vertices of the triangle. From the graph:
   - Vertex \( A \) is approximately at \( (-5, 0) \).
   - Vertex \( B \) is approximately at \( (5, 0) \).
   - Vertex \( C \) is approximately at \( (0, 8) \).

2. **Calculate the perpendicular bisectors of two sides**:
   The circumcenter is the point where the perpendicular bisectors of the triangle’s sides intersect. Let's find the perpendicular bisectors of sides \( AB \) and \( AC \).

   - **For side \( AB \)**:
     - Midpoint of \( AB \) is \( \left(\frac{-5 + 5}{2}, \frac{0 + 0}{2}\right) = (0, 0) \).
     - The slope of \( AB \) is \( \frac{0 - 0}{5 + 5} = 0 \).
     - A perpendicular line to \( AB \) (with undefined slope) passing through \( (0, 0) \) is simply the **y-axis**, or \( x = 0 \).

   - **For side \( AC \)**:
     - Midpoint of \( AC \) is \( \left(\frac{-5 + 0}{2}, \frac{0 + 8}{2}\right) = \left(-2.5, 4\right) \).
     - The slope of \( AC \) is \( \frac{8 - 0}{0 + 5} = \frac{8}{5} \).
     - The perpendicular slope to \( AC \) is \( -\frac{5}{8} \).
     - Using the point-slope form \( y - y_1 = m(x - x_1) \) with point \( (-2.5, 4) \) and slope \( -\frac{5}{8} \):
       \[
       y - 4 = -\frac{5}{8}(x + 2.5)
       \]
       Simplifying this equation will give us the line of the perpendicular bisector of \( AC \).

3. **Find the intersection of the perpendicular bisectors**:
   - Solve the equations of the perpendicular bisectors of \( AB \) and \( AC \) to find the circumcenter.

Since the perpendicular bisector of \( AB \) is \( x = 0 \), we substitute \( x = 0 \) into the equation derived for the bisector of \( AC \) to find the circumcenter’s coordinates.

After calculations, the circumcenter is approximately at **(0, 4)**.
