Line Symmetry And Reflections

Hello....Again. I hope im not posting to many questions....I joined this site to learn more about math since im really not good at it.

I have a lot of trouble figuring out how to reflect coordinates of a number.

If you have a number like (6,1) than its mirror image would be (6,-1) right?

Thanks For All The Help,

Shyclaw

Re: Line Symmetry And Reflections

If you are reflecting in the x-axis, then yes.

However, using a different axis of reflection will give you a different 'mirror image'. For instance, if you were reflecting in the y-axis instead, the 'mirror image' of (6,1) would be (-6, 1).
