Is this the correct answer yes or no
C= (F-32)*5/9=8.3, or (47-32)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
    F-32 = (9/5)C
    C = (5/9)(F-32) checks with you

    If C = 8.3 deg C
    then
    F = (9/5)(8.3) + 32
    F = 47 deg F
