Parallelogram ABCD is rotated 90 degrees counterclockwise. What rule shows the input and output of the rotation and what is the new coordinate of A (-5, 1)?

Complete Question:

Parallelogram ABCD is rotated 90° counterclockwise. What rule shows the input and output of the rotation, and what is the new coordinate of A(-5, 1)? a. (x,y) → (-x, -y); A' is at (5, -1)

b. (x,y) → (-y, x); A' is at (-1,-5)

c. (x, y) (y, -x); A' is at (1,5)

d. (x,y) → (X, -y); A' is at (-5, -1)

option b

Step-by-step explanation:

rotated 90 degrees counterclockwise

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

(-5,1) => (-1, 5)
