URGENT QUESTION PLEASE HELP ME! about coordinate rules

thank you so much! but, what do you mean by flipped over? 

Another word is "reflected."

For example:

If you take  (3, 7)  and make its x-coordinate negative, you will get  (-3, 7) .

Maybe you can imagine that this graph is an open book where the y-axis is the division between two pages.

If you flipped the page, then the two points would meet.

If you took  (3, 7)  and flipped it over the y-axis (like flipping the page), you would get  (-3, 7) .

So  (-3, 7)  is  (3, 7)  flipped over the y-axis.

And you can see that the distance between  (3, 7)  and the y-axis is the same as the distance between  (-3, 7)  and the y-axis.

Does that kind of make sense? 

I like to call it the oppsite of the Number on the cordinate grid say you have (1,-1) well its oppsite is (-1,-1) 

or say we have (6,5) well its oppsite or as hectictar had explained how she calls it reflected is (-6,5) 

Also to count on a graph you just count each corrdinate across.  See because I counted it the to points are 6 corrdinates apart.....   Oh yeah thanks hectictar for your image I saved it and did that on it hope your not mad or anything XD

yes thank you! so like would lets say for example (3,7) and have that for point a and (-3,7) for A' so would the coordinate rule of that just be 
(x,y)----> (-x,y)?

I mean (8,5) and (-8,5)

Was this a trick question beause I never said that???? 

But if you were looking for there oppsites you could flip it over the x axcis instead of the (y) axcis so instead of left or right you could flip going down 

Maybe it's a trick question. I was just trying to get you to think.

There isn't a single defined "opposite" of  (8, 5) .

Instead of just saying  " (8, 5)  is the opposite of (-8, 5) "  we need to say something like

(8, 5)  is the opposite over the y-axis of  (-8, 5)

and

(8, 5)  is the opposite over the x-axis of  (8, -5)

It is important to say which axis that the point is "flipped" over.

I agree but Iguess I left that out I will remeber that... Thanks
