Answer 1

To rotate a point \((x, y)\) counterclockwise by \(270\) degrees about the origin, we can follow the rule for rotation:

• A \(90\) degrees counterclockwise rotation transforms the point \((x, y)\) to \((-y, x)\).
• A \(180\) degrees counterclockwise rotation transforms the point \((x, y)\) to \((-x, -y)\).
• A \(270\) degrees counterclockwise rotation is equivalent to a \(90\) degrees clockwise rotation, which transforms the point \((x, y)\) to \((y, -x)\).

Using the point \((5, 8)\):

1. For \(270\) degrees counterclockwise rotation (or \(90\) degrees clockwise): \[ (5, 8) \rightarrow (8, -5) \]

Thus, the new point after a \(270\) degrees rotation counterclockwise about the origin is \((8, -5)\).

The correct response is:

\((8, -5)\)
