(i) The reflection in origin is given by MO (x, y) = (-x, -y).
A’ = reflection of A (4, 6) in the origin = (-4, -6)
The reflection in y-axis is given by My (x, y) = (-x, y).
A” = reflection of A’ (-4, -6) in the y-axis = (4, -6)
(ii) The reflection in x-axis is given by Mx (x, y) = (x, -y).
The reflection of A (4, 6) in x-axis is (4, -6).
Thus, the required single transformation is the reflection of A in the x-axis to the point A”.
