The image of C reflected over the x-axis
Graph the given reflection The image of C reflected over the x-axis 7.2 Reflections
5
The D is on the y-axis, a reflection over it would be the same point
Graph the given reflection The D is on the y-axis, a reflection over it would be the same point 7.2 Reflections

The image of E reflected over the line y = 3
Graph the given reflection The image of E reflected over the line y = 3 7.2 Reflections
7
Graph the given reflection
Since F is on the line y = -2, a reflection over it would be the same point 7.2 Reflections
