MCQ

Find mirror image of point representing x + i y on real axis:

A
(x, y)
B
(-x, -y)
C
(-x, y)
D
(x, -y)

✓

Answer

(x, -y)

Solution:

Mirror image of point (x, y) on real axis is (x, -y).

Since real axis is acting as mirror x-coordinate remains same whereas y-coordinate gets inverted.

So, (x, -y) is mirror image of (x, y) on real axis.
