To rotate a point \( (x, y) \) 90 degrees clockwise around the origin, you can use the transformation:
\[ (x, y) \rightarrow (y, -x) \]
Given point \( A(2, 6) \):
- Identify \( x = 2 \) and \( y = 6 \).
- Apply the transformation: \[ (x, y) \rightarrow (y, -x) \Rightarrow (6, -2) \]
So, after a rotation of 90 degrees clockwise, point \( A(2, 6) \) will be located at the new point \( (6, -2) \).
