Question

A point is reflected over the y-axis, but the x-coordinate does not change. What is the location of the point?

Answer 1

Answer:

Let the initial coordinates of the point be 3,4

Since the x coordinate doesn't change, incidence is perpendicular to the Y axis. Therefore distance of the image is same as the distance of the object from the Y axis. After reflection the location is same as the position of the object 3,4
