Warm UP: Reflections

State the line of reflection.

• Reflection across y-axis
• Reflection across x-axis
• Reflection across x = 1
• Reflection across y = 1

Find K' if the figure is reflected across the x-axis

• (4, 1))
• (-1, -4)
• (1, -4)
• (1, 4)

What are the coordinates for A' after a reflection over the line y=x?

• (-5,2)

• (2,-5)

• (5,2)

• (2,5)

A preimage has point A located at (2,7). What are the coordinates for point A' after reflecting over the line y=-x? (Write your answer without spaces)

(a)  

What shape is the reflection from shape E over the x-axis?

• A

• C

• B

When reflecting over the y-axis, the ​ (a)   stays the same and the ​ (b)   becomes opposite.

• y
• x

Reflect (6, -3) over the line y = -x and then over the x-axis.

• (6, 3)

• (-6, -3)

• (-3, 6)

• (3, 6)
