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?

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.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
