Will give brainliest if correct! the line segment shown is rotated 90° about the origin (counterclockwise). what are the new coordinates of point a? a) (2, 1) b) (-2, 1) c) (-2, -1) d) (1, 2)

Point A before being rotated = (1,-2)

A point (x,y) is rotated counterclockwise by 90°. The result will be (-y,x)

If point (1,-2) rotated counterclockwise by 90°, the result will be (2,1)

ANSWER: A. (2,1)

Answer is either b or c
