Answer:
A'(-5, 7), B'(4, 7) and C'(-5, -2)
Step-by-step explanation:
Given: The reflection is over the line g with the equation y = x.
Coordinates are A(7,-5), B(7,4) and C(-2,-5).
We know that if the point (x, y) is reflection over the line y = x, then the reflection point is (y, x)
We need to interchange the value of y and x of the original coordinates to find reflection points over the line y = x.
Therefore, the reflection vertices of the triangle are:
A'(-5, 7), B'(4, 7) and C'(-5, -2)
