Find the coordinates of the vertices of triangle PQR after a dilation with scale factor 3/2 and center at the origin.

I can't put in the picture, but the vertices are these:

. . .P = (4, 4)
. . .Q = (-2, 2)
. . .R = (0, 2)

I did:

. . .origin = Dk(x, y) = (kx, ky)

I got half answer right when I put:

. . .P = (6, 6)
. . .Q = (-3, 3)
. . .R = (0, 3)

Please help. Thank you!
