a triangle is rotated 90° about the origin. which rule describes the transformation?\n(x, y) → (-x, -y)\n(x, y) → (-y, x)\n(x, y) → (-y, -x)\n(x, y) → (y, -x)

a triangle is rotated 90° about the origin. which rule describes the transformation?\n(x, y) → (-x, -y)\n(x, y) → (-y, x)\n(x, y) → (-y, -x)\n(x, y) → (y, -x)

Answer

Explanation:

Step1: Recall rotation rule

When a point $(x,y)$ is rotated 90° counter - clockwise about the origin, the new coordinates are $(-y,x)$.

Answer:

B. $(x,y)\to(-y,x)$
