Question

Figure ABCD is a parallelogram with point C (−4, 1). What rule would rotate the figure 90 degrees counterclockwise, and what coordinate would be the output for point C'?

(x, y) → (y, −x); C' (1, 4)

(x, y) → (y, x); C' (1, −4)

(x, y) → ( −y, x); C' (−1, −4)

(x, y) → ( −y, −x); C' (−1,4)

Answer 4

rule for 90 degree rotation :

`(x, y) --> (-y, x)`

Answer 5

oh because you change it yo negative -4 turns to positive 4 So its A

Answer 6

?

Answer 7

it is C

Answer 8

what oho i see wy thx
