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 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?
