Question

If point (m,n) is reflected over the y–axis, what are the coordinates of its image?

Answer 1

assume that the coordinates are like for instance (2,3) the y coordinate i.e (0,3) will remain the same as it is reflected from its axis the x coordinate i.e (2,0) will change it is reflected so the new coordinate will be (-m,n) i.e (-2,3) as example.
