Answer:

f = -
(19)/(7)

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 that f = - 19 when m = 14, thus

- 19 = 14k ( divide both sides by 14 )

-
(19)/(14) = k

f = -
(19)/(14) m ← equation of variation

When m = 2, then

f = -
(19)/(14) × 2 = -
(19)/(7)
