Math Problem Statement
Write a rule to describe the transformation.
Solution
The transformation shown in the image appears to be a reflection. To determine the correct reflection, let's analyze the coordinates:
- The original shape (black) is reflected to the new shape (blue).
- The transformation switches the signs of both x and y coordinates.
- This corresponds to a reflection across the line , where the transformation rule is .
The correct answer is C) reflection across .
