Question
The image depicts a coordinate plane with two triangles: a pre-image triangle labeled \( \triangle ABC \) and its translated image \( \triangle A'B'C' \).

### Description:

- **Pre-Image Triangle \( \triangle ABC \):**
  - Positioned in the coordinate space with vertices at points:
    - \( A(2, 2) \)
    - \( B(5, 6) \)
    - \( C(7, 2) \)

- **Image Triangle \( \triangle A'B'C' \):**
  - Result of translating the pre-image. Positioned with vertices at:
    - \( A'(2, 5) \)
    - \( B'(5, 9) \)
    - \( C'(7, 5) \)

### Translation Rule:

The translation from the pre-image to the image can be described by the rule: 
\[ (x, y) \rightarrow (x, y+3) \]
This indicates that each point of the pre-image is shifted upward by 3 units on the y-axis.

### Problem Statement:

5. **Write a rule for the translation of a point of the plane figure above.**

This involves understanding the positional shift applied to each vertex of the pre-image triangle to obtain the image triangle, specifically by examining the vertical shift observed on the coordinate plane.

**Question 5: Translation Rule for a Point on a Plane Figure**

Select the correct rule for translating a point of the plane figure.

Options:

A. \((x, y) \rightarrow (x - 2, y + 3)\)

B. \((x, y) \rightarrow (x + 2, y + 3)\)

C. \((x, y) \rightarrow (x - 2, y - 3)\)

D. \((x, y) \rightarrow (x + 3, y - 2)\)

**Explanation:** In each option, the rule indicates how the coordinates \((x, y)\) of a point are transformed. The expression on the right side of the arrow \((x', y')\) shows how the original point is moved in the coordinate plane. For example, in option A, the point is moved 2 units left and 3 units up.
