Question

Find the co-ordinates of the images of the following under reflection in the origin:
(3, -7)

Answer 1

The reflection (image) of the point P(3, -7) at the origin is the point P'(-3, 7).
Note: To find the reflection of a point in the origin change: (a) The sign of abscissa; i.e., X co-ordinate. (b) The sign of ordinate; i.e., Y co-ordinate.
