For the dilation, DO, K = (10, 0) → (5, 0), the scale factor is equal to _____.
2 answers:
Answer:
The scale factor is
.
Step-by-step explanation:
The dilation of a point about the origin with scale factor k is defined as
..... (1)
It means the scale factor is calculated as

The given dilation is defined as
..... (2)
From (1) and (2) we get,
x coordinate of image = 5
x coordinate of preimage = 10


Therefore the scale factor is
.
Scale factor is equal to 1/2, since the point went from 10 to 5
