Question

Huy rotated the figure 90 degrees counterclockwise about the origin. What are the new coordinates of point C?
(–5, –1)
(–1, 5)
(1, –5)
(5, –1)

Answer 1

Step-by-step explanation:

90° counterclockwise = 270° clockwise

Algebraic Representation : 270° clockwise turn,

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

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