What is a reflection?

• When you turn an object around a point.

• When you slide an object form one place to another.

• When you flip or mirror an object across a line.

• When you resize an object.

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

• x-axis

• x-coordinate

• y-coordinate

• none of the above
