Question

a rectangle was rotated 270° about the origin. the image is shown. which points are vertices of the pre - image? choose two correct answers. this question requires at least 2 answers. n(-3,1) k(-3,-1) m(3,2) m(-3,2) n(3,1)

Explanation:

Step1: 270° rotation rule

Pre-image (x,y) → Image (y,-x). Thus, Image (x',y') → Pre-image (x,y)=(-y',x').

Step2: Check options

Assume image vertices, apply inverse rotation to match pre-image options. M(3,2) and N(-3,1) are valid pre-images.

Answer:

M(3,2), N(-3,1)
