Solution

Given: the image of a point $P (2, 3)$ under reflection in the origin is $P^{'} (x, y)$ .

We know when a point is reflected in the origin, the sign of its ordinate and abscissa changes.
$[1 M a r k]$

Hence, the coordinates of the image of point $P (2, 3)$ under reflection in the origin are $P^{'} (- 2, - 3)$ .
$[1 M a r k]$

Thus, $x = - 2$ and $y = - 3$ .
$[1 M a r k]$
