Coordinate Plane Reflections

​When a point is reflected over the x-axis, it appears to move up or down.

​

​

​

​When a point is reflected over the y-axis, it appears to move left or right.

​

​

​

Multiple Choice

Which axis is the line of reflection?

• x-axis

• y-axis

Multiple Choice

Which axis is the line of reflection?

• x-axis

• y-axis

Multiple Choice

Which axis is the line of relfection?

• x-axis

• y-axis

​a. What is the line of reflection?

​

​

​b. What quadrant is the pre-image?

​

​

​c. What quadrant is the new image?

​

​

​d. What do we notice about the ordered pairs?

​When we reflect over the x-axis, the y coordinate becomes it's opposite

​

​When we reflect over the y-axis, the x coordinate becomes it's opposite.

​

​

​A general rule to remember, whatever axis you are reflecting over, the opposite coordinate becomes it's opposite.
