Answer:
f = -
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
- 19 = 14k ( divide both sides by 14 )
- = k
f = - m ← equation of variation
When m = 2 , then
f = - × 2 = -
