Five points are plotted on the coordinate plane.

## Question 1

a. Using the Pen tool or Text tool , label each point with its coordinates.
b. Using the -axis as the line of reflection, plot the image of each point.
c. Label the image of each point with its coordinates.
d. Include a label using a letter. For example, the image of point should be labeled .

## Question 2

If the point were reflected using the -axis as the line of reflection, what would be coordinates of the image? What about ? ? Explain how you know.

## Question 3

The point has coordinates . a. Without graphing, predict the coordinates of the image of point if point were reflected using the -axis as the line of reflection. b. Check your answer by finding the image of on the graph.

c. Label the image of point as . d. What are the coordinates of ?

## Question 4

Suppose you reflect a point using the -axis as the line of reflection. How would your describe its image?
