To reflect a point over the y-axis, you change the sign of the x-coordinate while keeping the y-coordinate the same.
Point K is located at (-2, 1).
To reflect this point over the y-axis:
- The x-coordinate (-2) becomes 2.
- The y-coordinate (1) remains the same.
Thus, the coordinates of the image of point K after reflection, K', are (2, 1).
Therefore, the correct answer is \( K'(2, 1) \).
