1. Since H is 4 units to the left of the y-axis,
Reflections
COURSE 3 LESSON 3-9
Graph the point H (–4, 5). Then graph its image after it is reflected over the y-axis. Name the coordinates of H .
Since H is 4 units to the left of the y-axis,
The coordinates of H are (4,5).
H is 4 units to the right of the y-axis.

2. Reflect the other vertices. Since B is 1 unit above the x-axis,
Reflections
COURSE 3 LESSON 3-9
BCD has vertices B (–3, 1), C (–2, 5), and D (–5, 4). Graph BCD and its image after a reflection over the x-axis. Name the coordinates of the vertices of B C D .
Draw B C D .
Reflect the other vertices.
Since B is 1 unit above the x-axis,
B is 1 unit below the x-axis.
The coordinates of the vertices are B (–3, –1), C (–2, –5), and D (–5, –4).
