Question

answer
a reflection over the line y = -x
a reflection over the line y = x
a clockwise rotation of 270° about the origin
a clockwise rotation of 180° about the origin

Explanation:

To determine the transformation from figure A to B, analyze key coordinate changes. Reflection over \( y = x \) swaps \( (x, y) \) to \( (y, x) \), matching typical positional relationships of such figures on a coordinate plane. Other options (reflection over \( y=-x \), 270°/180° rotations) do not align with standard positional mappings for this setup.

Answer:

A reflection over the line \( y = x \)
