Find the image of point (2, 3) under

(i) X-axis

(ii) Y-axis

(iii) origin.

(i) We know that, if X-axis is mirror, then sign of y-coordinate will be changed and sign of x-coordinate will remain same.

X-axis = (2, -3)

(ii) If Y-axis is mirror, then sign of x-coordinate will be changed and sign of y-coordinate will remain same.

Y-axis = (-2, 3)

(iii) If origin is taken as mirror, then signs of both coordinates will be changed.

So, image of point (2,3) under

∴ Origin = (-2,- 3)
