It is helpful to first plug this in to point-slope form (note that there are other ways to do this).
Using the form

, you get

. You can simplify this to get

the number is 40.
A = 40
:D
We are given

Since, we have to solve for F
so, we will isolate F on anyone side
step-1:
Multiply both sides by 60


step-2:
Divide both sides by 11


step-3:
Add both sides by 32


so, we get
