IM 8.1.5.2: Reflecting Points on the Coordinate Plane

Five points are plotted on the coordinate plane.

Question 1

a. Using the Pen toolToolbar Image or Text tool Toolbar Image, 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?
