Coordinate Plane, Reflections, and Distance

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

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

Reflect about the y -axis
(-3 , -6)

• 3,6
• -3,6
• 3,-6
• 3,6

What does this show?

• reflection over the y-axis
• reflection over the y-coordinate
• reflection over the x-axis 
• reflection over the x-coordinate

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

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

What happens to a coordinate when it is reflected over the y-axis?

• x and y stay the same
• x stays the same and y changes to its opposite
• x changes to its opposite and y stays the same
• both x and y change to their opposites

Reflect point G across the x-axis. What are the new coordinates?

• (4, 2)

• (-4, -2)

• (-4, 2)

• (4, -2)
