Find mirror image of point representing x + i y on imaginary axis:
  • A
    (x, y)
  • B
    (-x, -y)
  • C
    (-x, y)
  • D
    (x, -y)

Answer

  1. (-x, y)

Solution:

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

Since imaginary axis is acting as mirror y-coordinate remains same whereas x - coordinate gets inverted.So, (-x, y) is mirror image of (x, y) on imaginary axis.
