Answer:
P'(1, 1), Q'(2, 2), R'(4, 1)
Step-by-step explanation:
The dilation factor multiplies each coordinate value, so ...
P' = (1/2)P = (2/2, 2/2) = (1, 1)
Q' = (1/2)Q = (4/2, 4/2) = (2, 2)
R' = (1/2)R = (8/2, 2/2) = (4, 1)
Each point is half as far from the origin as the original. Here, all of the PQR coordinates are even numbers, so dividing them by 2 is about as easy as it gets.
