### Reflections in a Line

Exercises on Reflections in a Line

Complete.

1. Given triangle FNR with coordinates
F(-2, 0), N(6, 0), and R(4, 0), find the image of point N after a reflection in the x-axis.
2. After a reflection in the x-axis, (10,-3) is the image of point E. What is the original location of point E?
3. The reflection of M (-2,2) is M' (2,2). What is the reflection of L (12,1), if the point is reflected using the same reflection line?
4. The reflection of I (0,9) is I' (0,-9). What is the reflection of K (8,-6), if the point is reflected using the same reflection line?
5. Given triangle HMG with coordinates
H(1, -12), M(6, 1), and G(2, 5), find the image of point G after a reflection in the line y=x.
6. Given triangle EFU with coordinates
E(-9, 12), F(0, -1), and U(1, 10), find the image of point F after a reflection in the y-axis.
7. After a reflection in the line y=x, (3,-1) is the image of point M. What is the original location of point M?
8. After a reflection in the y-axis, (4,-7) is the image of point N. What is the original location of point N?
9. The reflection of P (3,-2) is P' (-2,3). What is the reflection of C (-9,3), if the point is reflected using the same reflection line?
