X-Axis Reflections
Figure is flipped across the x-axis.
Point A and Counterpart Point D
Point A ( 2, 1), whereas Point D ( 2, -1)
What do you notice?
Rule: ( x, - y )
The x value remains the same, y value gets the opposite sign.
4
Y-Axis Reflections
Figure is flipped across the y-axis
Let's look closer at B and B'
Point B ( 5, 2) and Point B' ( -5, 2)
What do you notice?
The y values remained the same and x values have the opposite sign.
Rule: ( -x, y )

( 3, -2)
Reflect this point over the x-axis and put your answer in the chat box.
Find Point Q
( 1, - 2)
Reflect this point over the y-axis and put your answer in the chat box.
