Math Problem Statement
Question Amy is making a map. She wants to reflect Point across the y-axis. What are the coordinates of its reflection?
Enter the correct answer in the boxes.
Solution
To reflect a point across the -axis, we change the sign of the -coordinate while keeping the -coordinate the same.
The given point is .
Reflection rule:
- becomes .
Applying the rule:
- The -coordinate is , so its reflection is .
- The -coordinate is , and it remains unchanged.
Thus, the reflection of across the -axis is:
Final Answer:
Do you want a detailed explanation or examples of similar reflections?

- What is the general formula for reflecting across any line (like )?
- Can you explain why the -coordinate remains unchanged in this type of reflection?
Tip:
When reflecting across the -axis, focus only on flipping the sign of the -coordinate; the -coordinate always stays the same!
