Analyze Reflection

What axis is the image reflected over?

• X-axis

• Y-axis

What happens to the x- and y-coordinates of a point, if it is reflected over the x-axis?

• The x-coordinate stays the same and the y-coordinate changes the sign.

• The x-coordinate changes the sign and the y-coordinate stays the same.

• The x-coordinate and the y-coordinate stay the same.
