Answer:

No, a Celsius temperature is not proportional to its equivalent Fahrenheit temperature.

Explanation:

The formula is

#F = 9/5C + 32#

#F# increases as #C# increases and #F# decreases as #C# decreases, but the relation is not a direct proportionality.

In mathematics, a direct proportion has the form

#y = mx#,

where #m# is a constant.

If the formula had been

#F = 9/5C#

it would have been a direct proportion.

However, the addition of the #+32# term makes the formula no longer a direct proportion.
