Answer:
rise over run (change in y divided by change in x)
so it would go as follows
![\frac{(3-1)}{(4-9)}](https://tex.z-dn.net/?f=%5Cfrac%7B%283-1%29%7D%7B%284-9%29%7D)
= ![\frac{2}{-5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B-5%7D)
= ![-\frac{2}{5}](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7B5%7D)
Answer:
16
Step-by-step explanation:
f(x) = 1/3x + 8
f(-12) =1/3(-12) + 8
f(-12) = -4 + 8
f(-12) = 4
3f(-12) + 4
3(4) + 4
12 + 4
