- A(2, 6)
- B(−2, −6)
- C(2, −6)
- D(6, −2)
Step-by-Step Solution
Reflecting in the -axis keeps the same and changes the sign of : (−2, 6) → (2, 6).
Answer: A) (2, 6)
The reflection of the point (−2, 6) in the -axis is:

Key idea: Special points
- **Origin**: (0, 0).
- **On -axis**: , so the form is (a, 0). Examples: (3, 0), (−5, 0).
- **On -axis**: , so the form is (0, b). Examples: (0, 7), (0, −2).
- **First-quadrant point**: both positive.
- **Third-quadrant point**: both negative.
Knowing which axis or quadrant a point belongs to is a quick check that you've plotted it correctly.
