Solution

Given,

The point (-3,0) is the image of point (3, 0) and point (2, -3) is image of point (-2, -3) reflected on the same line.

(i) Clearly, it’s seen that the mirror line will be y-axis.

(ii) The co-ordinates of the image of the point (-3, -4) reflected in the same line i.e. y-axis will be (3, -4).
