1. Reflecting Across the X and Y

2. Record the ordered pairs for each point of Rectangle ABCD
Rectangle ABCD Points
Reflection across the x-axis
A(-5, -2)
B(-3, -2)
C(-3, -5)
D(-5, -5) A B D C

3. Reflection across the x-axis
Plot and label the reflection of each point across the x-axis. Connect the points to form a rectangle. Record the ordered pair of the reflection in the table you created. D C
Rectangle ABCD Points
Reflection across the x-axis A B
A(-5, -2)
B(-3, -2)
C(-3, -5)
D(-5, -5)
A’(-5, 2)

C’(-3, 5)
D’(-5, 5) D C
How do the coordinates of an ordered pair change when the point is reflected across the x-axis? Explain.

4. When the point is reflected across the x-axis:
x-coordinate stays the same
y-coordinate changes sign (becomes the opposite) D C
