Answer:
Answer is reflection across line. When transformation maps X"Y"Z" .Then first transformation for this composition is , and the second transformation is 90° rotation about point X'.
Explanation:
When you transform a point across a line y=x then x-coordinate and y-coordinate changes.
Similarly when you reflect a point across the line y=-x then signs are changed and both coordinate change places.
It is the first transformation across the line.
