A triangle is rotated 90° about the origin. Which rule describes the transformation? (x, y) (-x, -y)
O(x, y) (-y, x)
(x, y) (-), -x)
(x, y) →ly, -x)

(x,y) -> (-y,x), second option.

Step-by-step explanation:

Rotation of 90 degrees about the origin:

The rule for a rotation of a point (x,y) 90 degrees about the origin is given by:

(x,y) -> (-y,x)

This is that the question asks, and so, this is the answer, which is the second option.
