Answer:
D
Step-by-step explanation:
Under a clockwise rotation about the origin of 90°
a point (x, y ) → (y, - x ), thus
C(1, 2 ) → C'(2, - 1 ) → D
Answer:
option D
Step-by-step explanation:
C (1, 2) is rotated 90° clockwise
When (x,y) is rotated 90 degree clockwise then
(x,y) becomes (y,-x)
Interchange the value of x and y and multiply the x value by negative sign
C (1, 2) becomes (2,-1) that is C'
So , C (1, 2) is rotated 90° clockwise is C' (2,-1)
