Answer:
f = - ![\frac{19}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B7%7D)
Step-by-step explanation:
Given f varies directly with m then the equation relating them is
f = km ← k is the constant of variation
To find k use the condition f = - 19 when m = 14, thus
- 19 = 14k ( divide both sides by 14 )
-
= k
f = -
m ← equation of variation
When m = 2, then
f = -
× 2 = - ![\frac{19}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B7%7D)
