Question

the point p (4,2) is rotate to become p(-2,4). describe the rotation by degree and direction. (1 point)
90° rotation
−90° rotation
−270° rotation
180° rotation

Explanation:

Step1: Recall 90° counterclockwise rotation rule

For (x,y), 90° rotation: (-y,x)

Step2: Apply to P(4,2)

(-2,4) = P'(-2,4)

Answer:

90° rotation
