A quadrilateral with vertices at A(4, –4), B(4, –16), C(12, –16), and D(12, –4) has been dilated with a center at the origin. Th
e image of D, point D prime, has coordinates (36, –12). What is the scale factor of the dilation?

Answer:
3
Step-by-step explanation:
The scale factor multiplies each coordinate value. If the scale factor is k, then we have ...
D' = kD
(36, -12) = k(12, -4) = (12k, -4k)
k = 36/12 = -12/-4 = 3
The scale factor of the dilation is 3.
