Question 1139974: Reflect this triangle over the line y=-x
Point A (2,1) Point B (2,3) Point C (3,1)
The notes are confusing me, and I am currently waiting for my teacher to email me back. I am still trying nut any help is greatly appreciated. Thank you!

The line of reflection is y = -x. That means in the reflection of a point (p,q) the new y value is -p.
The line of reflection is also x = -y (solve the given equation for x). That means in the reflection of a point (p,q) the new x value is -q.
So the image of a point (p,q) in a reflection in the y=-x is (-q,-p).
A(2,1) --> A' = (-1,-2)
B(2,3) --> B' = (-3,-2)
C(3,1) --> C' = (-1,-3)
