The image after a dilation with a scale factor of 3 is A(-6, -3), B(0, 3), and C(3, -9) of triangle ABC.

Here, the coordinates are,

D = (-2, -1)

E = (0 , 1)

F = (1, -3)

After dilating triangle DEF using a scale factor of 3 and a center of dilation at the origin to form triangle ABC.

A = (-2 x 3, -1 x 3) = (-6, -3)

B = (0 x 3, 1 x 3) = (0, 3)

C = (1 x 3, -3 x 3) = (3, -9)

Line segments,

AB = 8.48

BC = 12.36

CD = 10.81

Therefore, after dilation by using a scale factor of 3 is  A(-6, -3), B(0, 3), and C(3, -9).
