Is the picture being reflected in the y-axis or x-axis?

• y-axis
• x-axis

Triangle ABC has vertices A(5,2).  Find the coordinates of ABC after a reflection over the x-axis.

• A’(5, -2)
• A’(-5, -2)
• A’(-5, -2)
• A'(5,2)

Reflecting over the y-axis changes the ____-_____________. 

• x-axis
• x-coordinate
• y-coordinate
• none of the above

Reflections over the x-axis change the ____-__________. 

• y-coordinate
• x-coordinate
• y-axis
• x-axis 

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)

Reflect the point (2, -4) over the y-axis.

• (-4, 2)
• (-2, 4)
• (-2, -4)
• (2, 4)

Reflect (6, -3) over the x-axis.

• (6, 3)
• (-6, -3)
• (-3, 6)
• (3, -6)

You want to reflect a figure over the horizontal line shown. 
What line are you reflecting over? 

• x = -4
• y = -4
• x - y = 4
• None of these

B(-2, -4)
Reflect over the line y = x

• (2, -4)
• (-4, 2)
• (-4, -2)
• (4, 2)
