Is this the correct answer yes or no
C= (F32)*5/9=8.3, or (4732)x5*9= 8.3

(C,F)
(0,32)
(100, 212)
F = m C + b
m = (212 32)/100 = 180/100 = 9/5
so
F = (9/5) C + b
32 = (9/5)(0) + b
b =32
so
F = (9/5) C + 32
or
F32 = (9/5)C
C = (5/9)(F32) checks with you
If C = 8.3 deg C
then
F = (9/5)(8.3) + 32
F = 47 deg F
