Question

1. determine the correct answer. determine the coordinates for c after a 90 degree rotation counterclockwise.

Explanation:

Step1: Identify original coordinates of C

Assume C is (2, 1) from grid.

Step2: Apply 90° CCW rotation formula

$(x,y)
ightarrow(-y,x)$, so $C'=(-1,2)$.

Answer:

(-1, 2)
