Question

Please help explanation if possible

Answer 1

Explanation:

The equation for the direct variation is, for us (using f and m instead of y and x):

f = km, where k is the constant of proportionality. We need to solve for this first using the first set of given values:

-19 = k(14) so

`k=-(19)/(14)` Now plug that in with second set of givens, namely to find f when m is 2:

`f=(-(19)/(14))(2)` and

`f=-(19)/(7)`
