It should be -3 I hope this helps
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
Answer is #3
add up all the x’s
Answer would be B. Sorry if my handwriting is messy or if I didn’t explain enough
Solute = what is dissolved
solvent = that which dissolves or can dissolve
You take it from here.
