Answer:
The scale factor is

Step-by-step explanation:
Line segmentAB has vertices A(−3, 4) and B(1, −2) .
A dilation, centered at the origin, is applied to AB. The image has vertices
A'(-1,4/3) and B′(1/3, −2/3) .
We know the rule for dilation by scale factor of k, is

This means that;

But we know, A' has coordinates (-1,4/3)
This means that


We could also compare:
4k=4/3
Which gives
k=⅓
1/2 - 3/11
Set both denominators (bottom numbers) to 22, so multiply the numerator of 1/2 by 11, and multiply the numerator of 3/11 by 2.
1/2 is now 11/22
3/11 is now 6/22
So, our new question is now : 11/22 - 6/22
Because the denominators are the same, all you have to do is simplify the top numbers.
So, 11-6 = 5
Therefore, your answer is 5/22
