Reflections

8
Reflect across the x-axis Change the sign of the y-value

9
Reflect across the x-axis

10
Reflect across the y-axis Change the sign of the x-value

11
Reflect across the y-axis

12
Reflect across the line y = x Swap x and y

13
Reflect across y = x Reflect across the line y = x

14
Reflect across y = -x Swap and change both signs Reflect across the line y = -x
