3°C = 37.4°F
You've given the answer yourself. d=6 and f=3.
f = 54
3 degrees Celsius = 37.4 degrees Fahrenheit
If: df+10f = 3 Then: f(d+10) = 3 And: d = 3/f -10

The idea is to replace every "x" by "3", and then do the calculations.
20 equals Y that RVWS
3-e = 4-f f-e = 4-3 f-e = 1
The slope of f(x) = 3-4x is -4.
It is 1.2164
