Question

PLEASE HELP!!

Which scale factors produce an expansion under a dilation of he original image?

Choose all answers that are correct

a)-2
b)-1/2
c)1/2
d)2

Under the dilation, the point (3,5) is moved to (6,10)
What is the scale factor of the dilation?

Answer 1

For dilation's, you can ignore any negative signs.

An expansion would be a number greater than 1.

The correct answers would be a and b

The numbers double: 3 x 2 = 6, 5 x 2 = 10, so the scale factor is 2.
