If P is (-3, 4) and My  Mx (P) shows the reflectior of the point P in the x-axis and then the reflectior of the image in the y-axis, then My Mx (P) is

A) (3, 4)                    

B) (-3, -4)

C) (-3, 4)

D) (3, -4)

Correct Answer: D

Solution :

 \[\because \]  P is \[(-3,4)\] \[\therefore \] Reflection of P in the X-axis is                 \[{{M}_{x}}P=(-3,-4)\]                 Hence, the reflection of the image in the Y-axis is \[{{M}_{y}}{{M}_{x}}\] (P) is \[(3,-4)\].
