**Problem Statement:**

Find the center-radius form of the circle with center \((-12, -5)\) that passes through the point \((-7, 5)\).

**Solution:**

The center-radius form of the equation of the circle is [   ].

*(Type an equation. Simplify your answer.)*

**Explanation:**

Given the center \((-12, -5)\) and a point \((-7, 5)\) on the circle, you can find the radius by calculating the distance between the center and the given point using the distance formula:

\[ 
r = \sqrt{(-7 - (-12))^2 + (5 - (-5))^2}
\]

Once you have the radius \(r\), substitute it and the center coordinates into the center-radius equation of a circle:

\[ 
(x + 12)^2 + (y + 5)^2 = r^2
\] 

Simplify your answer to obtain the final equation.
