Pentagon ABCDE is dilated according to the rule
DO,3(x,y) to create the image pentagon A'B'C'D'E', which is shown on the graph.
On a coordinate plane, pentagon A prime B prime C prime D prime E prime has points (negative 3, 6), (negative 0.5, 8), (2, 6), (1, 3), and (negative 2, 3).
What are the coordinates of point A of the pre-image?
(-1, 1)
(-1, 2)
(-9, 6)
(-9, 18)

The dilation about the origin with scale factor 3 maps (x,y) -> (3x,3y). So A' = (−3,6) = 3*(x,y) gives A = (−3/3,6/3) = (−1,2).
Answer: (−1, 2)
Answer: (−1, 2)
