Question

What are the coordinates of the image D(0.5, R) (3, 5) where R(1, –3) is the center of dilation?

Answer 1

(2 , 1)

Explanation:

dilation center: (1 , -3)

scale factor: 1/2 (0.5)

Final coordinate (x' , y') is the mid-point of segment (3 , 5) and (1 , -3)

x' = (3+1)/2 = 2

y' = (5 + -3) / 2 = 1
