Question

Which ordered pair could not be the coordinates for a clockwise rotation of the point W(-3, 4)?

(3, -4)
(4, 3)
(-4, -3)
(-4, 3)

Answer 1

Explanation:

Look at the picture.

Any pair of choice can be the coordinates of the rotation of the point

W (-3, 4) clockwise.

All points have the same distance from the beginning.

The formula of a distance between the origin and a point (x, y):

`d=√(x^2+y^2)`

W(-3, 4)

`d=√((-3)^2+4^2)=√(9+16)=√(25)=5`

(3, -4)

`d=√(3^2+(-4)^2)=√(9+16)=√(25)=5`

(4, 3)

`d=√(4^2+3^2)=√(9+16)=√(25)=5`

(-4, -3)

`d=√((-4)^2+(-3)^2)=√(9+16)=√(25)=5`

(-4, 3)

`d=√((-4)^2+3^2)=√(9+16)=√(25)=5`
