Question

Dilations
If ABCD is dilated by a factor of Į, the
coordinate of D' would be

Answer 1

9514 1404 393

Answer:

D'(2, -1)

Explanation:

Dilation about the origin by factor k multiplies each coordinate by that factor:

(x, y) ⇒ (kx, ky)

For k = 1/3, this is ...

(x, y) ⇒ (x/3, y/3)

D(6, -3) ⇒ D'(6/3, -3/3) = D'(2, -1)
