Answer:

The mirror image point of (-3,-1) on Y-axis will be (3,-1).

Step-by-step explanation:

  • Image by plane mirror has the following characteristics:

       (1) The image should be behind the mirror.

       (2)  Distance between mirror and object = distance between mirror and image.

       (3) Image must be erect.

       (3) Lateral inversion occurs in image.

  •  If we put a plane mirror on Y-axis then the value along Y-axis will be fixed  because of erectness. In image y' = -1 as the original point was.
  • Original point x = -3 , in mirror image the value of 'x' will remain same but the sign will change, so x' = +3.
  • The mirror image point = (x',y') = (3,-1)
