Samantha drew a map of the park in the her neighborhood. She graphed the point P (-3.5,-3.5) for the playground. The fountain if located at P’ which is P reflected over the y-axis. She wants to graph the picnic tables P” which is P’ reflected over the x-axis. Plot an label P, P’ and P” on the graph
P' would be located at (3.5, -3.5) and P" would be located at (3.5, 3.5)
