Triangle RST has the coordinates R (0.2), S (3.8), and T (6,2). Which of the following sets of points represents a dilation from the origin of triangle RST?
A. R’ (0, 2), S' (3, 48), T' (36, 2)
B. R’ (0, 2), S' (18,8), T’ (36,2)
C. R’ (0, 12), S' (18,48), T’ (36, 12)
D. R’ (6,8), S' (9, 14), T’ (12,8)

i'm pretty sure the second one is -4 and rational. the best way to solve is guess and check, or you may just know your multiplication facts really good.
