Answer:
Step-by-step explanation:
Triangle XYZ has been reflected across a line y = 1,
Therefore, line y = 1 will work like a mirror and all the distance of the points of the points from this line will be equal after the reflection about this line.
Distance of X from this line = 2 units
After reflection distance of X' from the line of reflection will be 2 units in opposite side.
Therefore, coordinates of X' will be (3, 3)
