Question

State the co-ordinates of the images of the following points under reflection in the $x$-axis:

(iii) $(0,6)$

Answer 1

Given point: $(0,6)$

Reflection in the $x$-axis, $M_x(x,y)=(x,-y)$

$\Rightarrow M_x(0,6)=(0,-6)$

$\therefore$The co-ordinates of the image of the given point under reflection in the $x$-axis are $(0,-6)$.
