Introduction

In mathematics, coordinate translation is a fundamental concept that deals with the movement of points from one location to another in a coordinate plane. This concept is crucial in various fields, including geometry, algebra, and calculus. In this article, we will explore the concept of coordinate translation and apply it to a specific problem involving the translation of a point.

What is Coordinate Translation?

Coordinate translation is the process of moving a point from one location to another in a coordinate plane. This movement can be horizontal, vertical, or a combination of both. The key concept in coordinate translation is that the x-coordinate remains unchanged, while the y-coordinate changes.

Types of Coordinate Translation

There are two types of coordinate translation:

Vertical Translation: This type of translation involves moving a point up or down in the coordinate plane. The x-coordinate remains unchanged, while the y-coordinate changes.
Horizontal Translation: This type of translation involves moving a point left or right in the coordinate plane. The y-coordinate remains unchanged, while the x-coordinate changes.

Problem: Translating Point A

The problem states that point A, located at (-2, 4), is translated down 6 units. We need to find the coordinates of A'.

Step 1: Understanding the Translation

The problem states that point A is translated down 6 units. This means that the y-coordinate of point A will decrease by 6 units.

Step 2: Applying the Translation

To find the coordinates of A', we need to apply the translation to the original coordinates of point A. The x-coordinate remains unchanged, while the y-coordinate changes.

Original coordinates of point A: (-2, 4)

Translation: down 6 units

New y-coordinate: 4 - 6 = -2

New coordinates of point A': (-2, -2)

Conclusion

In conclusion, the coordinates of A' are (-2, -2). This is because the x-coordinate remains unchanged, while the y-coordinate changes due to the translation.

Answer

The correct answer is A. (-2, -2)
