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

There u go love
Step-by-step explanation:
6 plus 6 is 12 then 12 plus 3 is 15 then 15 plus 3 and 3 is 21 then we do 21 plus 4.2 is 25.4 plus 3 is 28.4 hope this helps
