Reflections

What is the simplest way to understand a reflection?

• A scaling

• A translation

• A flip over a line

• A rotation

When reflecting a point over the x-axis, which coordinate changes?

• Neither coordinate

• X-coordinate

• Y-coordinate

• Both coordinates

How does the y-coordinate change when a point is reflected over the x-axis?

• It doubles

• It changes sign

• It remains the same

• It is divided by 2

What happens to the coordinates of a point when it is reflected over the line y = x?

• They double

• They are halved

• They switch places

• They remain the same

When reflecting over the line y = -x, what changes besides the coordinates switching places?

• Neither coordinate changes sign

• Both coordinates change sign

• The y-coordinate changes sign

• The x-coordinate changes sign
