Which points are invariant under a reflection in the line y = −2?
Reflection
3 marksDifficulty: Medium
The point P(a, b) is reflected in the x-axis to P'(3, −5). Find a and b, and then find the image of P in the origin.
Original Khojo Papers practice question — not from a past board paper.
Answer
a = 3, b = 5, and the image in the origin is (−3, −5).
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Reflection in the x-axis gives (a, −b) = (3, −5), so a = 3 and b = 5. Reflecting P(3, 5) in the origin gives (−3, −5).
