What rotation centered about the origin maps (4, −7) to (7, 4) ?

90° counterclockwise

180° counterclockwise

270° counterclockwise

Respuesta :

Answer:

  • A) 90° counterclockwise

Step-by-step explanation:

Preimage (4, - 7) and image (7, 4).

Rule applied:

  • (x, y) → (-y, x), this is a 90° counterclockwise rotation

Correct choice is A

Answer:

Option A

Step-by-step explanation:

90° counterclockwise rotation about origin rule is

  • (x,y)=(-y,x)

So here

  • (4,-7)

Rotate it

  • (-(-7),4)
  • (7,4)

Option A is correct
