Answer:
The coordinates of reflection image of Z are (3,4).
Step-by-step explanation:
If a figure reflected across the line x = a, then

XYZ is reflected across the line x = 3, so the reflection rule can be defined as

From the given figure it is clear that the coordinates of Z are (3,4). The coordinates of reflection image of Z are


Therefore the coordinates of reflection image of Z are (3,4).
