Answer:
Slope = 
Step-by-step explanation:
(x₁ , y₁) = (-9 , -4) & (x₂ ,y₂) = (-3, -6)
Slope = 
![= \frac{-6-[-4]}{-3-[-9]}\\\\= \frac{-6+4}{-3+9}\\\\= \frac{-2}{6}\\\\= \frac{-1}{3}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B-6-%5B-4%5D%7D%7B-3-%5B-9%5D%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-6%2B4%7D%7B-3%2B9%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-2%7D%7B6%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-1%7D%7B3%7D)
B) should be your answer
The first one (the one given), is 6 "points" (forgot what it's called sorry) from 0 on all sides. To dilate it 1/3, divide 6 and 3
6/3 = 2
The one's that have points that land on points with 2 in it is B
so B is your best answer
hope this helps
