Question

A point P (7,3) is reflected in the x-axis to point P’. The point P’ is further reflected in v-axis to point P” Find :
(i) the coordinates of P’
(ii) the co-ordinates of P”
(iii) the image of P (7, 3) in origin.

Graph

Solution

(i) Image of point P (7,3), when reflected in x-axis, is P’ whose coordinates will be (7,-3)

(ii) Image of point P’ (7,-3) when reflected in y-axis, is P” whose co-ordinates will be (- 7,-3)

(iii) The image of P (7, 3) in origin is P” whose coordinates are (- 7, – 3).
