Question

A point P is mapped onto P' under the reflection in the x-axis. P' is mapped onto P" under the reflection in the origin. If the co-ordinates of 

P" are (5,-2), write down the co-ordinates of P. State the single transformation that takes place.

Answer 1

P"= (5,-2), therefore, co-ordinates of P' = (-5, 2) and hence the coordinates of P = (-5,-2)

Single transformation = reflection in the y-axis
