This is NOTpartner work, this is for you and you alone to complete in silence to give me a better understanding of what YOU know.
We have ONEday to understand the concept of reflections.
You should be working at a level 0 and NOTsharing YOURhard work with others who are just trying to copy and not learn.
If you are talking, you will receive an automatic 0.
KEY:
(x,y) -> (x, -y): x value did not change, so it is a reflection over x –axis.
(x,y) -> (-x, y): y value did not change, so it is a reflection over y –axis.

Question 3
3.
What is the rule?
ex:
(x,y) -> (y,x)
Examples:
(x,y) -> (x, -y): x value did not change, so it is a reflection over x –axis.
(x,y) -> (-x, y): y value did not change, so it is a reflection over y –axis.
