What are the coordinates of E' that will justify ∆DEF ~ ∆D'E'F'?

Question

∆DEF ∆D'E'F'

D (0, 0) D' (0, 0)

E (3, 2) E' (x, y)

F (7, 6) F' (14, 12)

1. (-2,1)
2. (6,9)
3. (8,20)
4. (20,28)

Answer 1

2*(7,6) = (7,14), so 2*(3,2) = (6,4) should be the correct choice, but it is not one of the given choices...

Answer 2

Diana you need to read/study the material on translations, rotations, and dilations.
