Question

The mirror image of point P(2, 3) taken about the origin is point P'. Find the coordinates of P'.

• A. $(-\sqrt{7},-3)$
• B. $(-2,-\sqrt{7})$
• C. $(-2,-3)$
• D. (-3, -2)

Answer 1

The correct option is C

$(-2,-3)$

The point P is in the I quadrant when taking its mirror image about the origin, the point P' will be formed in the III quadrant. The point P is 2 units right of the origin and 3 units above of origin. Similarly the image of the point P i.e. P' will be 2 units left of origin and 3 units below of origin. Therefore the coordinates of point P' is (-2, -3).
