To find the new coordinates of the point (5, 8) after a 270-degree counterclockwise rotation about the origin, we can use the rotation transformation rules.

A 270-degree counterclockwise rotation can be understood as a 90-degree clockwise rotation. The rotation rule for a point (x, y) after a 90-degree clockwise rotation is given by the transformation:

\[ (x, y) \rightarrow (y, -x) \]

So for the point (5, 8):

  1. Apply the rotation: \[ (5, 8) \rightarrow (8, -5) \]

Therefore, the new coordinates after rotating (5, 8) by 270 degrees counterclockwise about the origin are (8, -5).

The correct response is:

\((8, -5)\)
