### Graph Translation Problem

**Question:**
What effect will changing the equation \( x^2 + y^2 = 36 \) to \( x^2 + (y + 3)^2 = 36 \) have on its graph?

**Options:**
A) slides 3 units left  
B) slides 3 units down  
C) slides 3 units up  
D) slides 3 units right  

**Answer Choices Selection:**
- O A
- O B
- O C
- O D

---

**Explanation:**

This problem is about understanding the geometric translation of graphs. Here, the translation involves shifting the center of the circle. 

- The original equation \( x^2 + y^2 = 36 \) represents a circle centered at (0, 0) with a radius of 6.
- The modified equation \( x^2 + (y + 3)^2 = 36 \) represents a circle with the same radius but its center moved.

In general, \( x^2 + (y - k)^2 = r^2 \) translates the circle vertically by \( k \) units. In this case, \( k \) is -3, hence translating the circle 3 units down. The correct answer is B) slides 3 units down.

This type of transformation is crucial to understand in Algebra and Geometry for dealing with the graphs of equations.
