ΔRST is dilated about the origin, O, to create ΔR'S'T'. Point R is located at (3, 9), and point R' is located at (1.2, 3.6). Which scale factor was used to perform the dilation?
the scale factor would be R'/R so 1.4/3 and 3.6/4) both lead to the answer 0.4 so the answer 0.4 (they should both be the same) so that is the answer; 0.4
