Which points are invariant under a reflection in the line y = −2?
Original Khojo Papers practice question — not from a past board paper.
Answer
Every point that lies on the line y = −2, that is every point of the form (x, −2).
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
A point is invariant under a reflection exactly when it lies on the mirror line.
