To rotate the point \((-3, -5)\) 270 degrees counterclockwise, we can use the following rotation rules:

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

Starting with \((-3, -5)\):

  1. Apply the rotation for 270 degrees counterclockwise (or 90 degrees clockwise): \[ (y, -x) = (-5, 3) \]

Thus, the new point after rotating \((-3, -5)\) 270 degrees counterclockwise is \((-5, 3)\).

The correct answer is: \[ \text{(−5, 3)} \]
