Question
**Title: Understanding Translations in Coordinate Geometry**

**Introduction:**
In coordinate geometry, a translation moves every point of a shape or object a constant distance in a specified direction. This is a common geometric transformation that preserves the shape and size of objects.

**Example Problem:**
Consider the following problem:

- Point \( P'(-6, -4) \) is the image of point \( P(-2, 3) \) after a translation. What is the image of point \( A(5, -1) \) after you apply the same translation?

**Steps to Solve the Problem:**

1. **Determine the Translation Vector:**
   First, identify the change in coordinates from point \( P \) to point \( P' \). 
   
   - Change in the x-coordinate: \( -6 - (-2) = -6 + 2 = -4 \)
   - Change in the y-coordinate: \( -4 - 3 = -7 \)
   
   Therefore, the translation vector is \(( -4, -7 )\).

2. **Apply the Translation Vector to Point A:**
   Use the translation vector to find the new coordinates for point \( A \).
   
   - New x-coordinate: \( 5 - 4 = 1 \)
   - New y-coordinate: \( -1 - 7 = -8 \)
   
   Thus, the image of point \( A(5, -1) \) after the translation is \( A'(1, -8) \).

**Conclusion:**
By determining the translation vector and applying it to a given point, we can find the resulting coordinates of the translated point. In this example, the image of point \( A(5, -1) \) after applying the same translation is \( A'(1, -8) \).

**Interactive Tool:**
Feel free to use the interactive tools provided below to experiment with translations by inputting different coordinates and observing the resulting transformations.

**Formatting Options:**
You can also format your results using bold, italics, or underline to emphasize important points.

**Diagram:**
Although this specific problem doesn't include a diagram, visualizing points and transformations on a coordinate plane can be helpful. Try plotting the points \( P(-2, 3) \), \( P'(-6, -4) \), \( A(5, -1) \), and \( A'(1, -8) \

**Reflection Over the X-Axis**

**Problem Statement:**
Find the coordinates of the reflection without using the coordinate plane. 
Reflect point \( P(4,6) \) over the x-axis.

**Solution:**

To reflect a point over the x-axis, you keep the x-coordinate the same while changing the sign of the y-coordinate. For point \( P(4,6) \):

1. Original coordinates of point \( P \): \( (4,6) \)
2. The reflection over the x-axis would yield the coordinates \( (4,-6) \).

So, the coordinates of the reflection of point \( P(4,6) \) over the x-axis are \( (4,-6) \).
