The correct option for a 90-degree counterclockwise rotation about the origin is:
**Option #1: (x,y)→(−y,x)**
So the answer is **Option #2** (this option has a mistake in the answer options provided for your question; the correct mapping should be (x,y)→(-y,x)).
In summary, if you were to rotate a point \((x, y)\) 90 degrees counterclockwise around the origin, it would move to \((-y, x)\). Therefore, the correct answer is:
**Option #2: (x,y) → (−y,x)**.
**Option #1: (x,y)→(−y,x)**
So the answer is **Option #2** (this option has a mistake in the answer options provided for your question; the correct mapping should be (x,y)→(-y,x)).
In summary, if you were to rotate a point \((x, y)\) 90 degrees counterclockwise around the origin, it would move to \((-y, x)\). Therefore, the correct answer is:
**Option #2: (x,y) → (−y,x)**.
