Write down the co-ordinates of the image of the point

$(3,-2)$

when: (i) reflected in the x-axis (ii) reflected in the y-axis

The co-ordinates of the According to the question: point are

$(3,-2)$

.

Now,

(i) Co-ordinates of the image reflected in x- axis will be

$\left( 3,\text{ }2 \right)$

(ii) Co-ordinates of the image reflected in y- axis will be

$\left( -3,\text{ }-2 \right)$
