Use the diagram to answer the question.

The thermometer above correlates Fahrenheit and Celsius temperature scales.

Which of the following sentences is true?

A. Fahrenheit and Celsius scales are inversely proportional.
B. Fahrenheit and Celsius scales are unrelated.
C. Fahrenheit and Celsius scales are directly proportional.
D. Fahrenheit and Celsius scales have a fixed offset.

Answer :

Final answer:

The Fahrenheit and Celsius temperature scales have a relationship that is directly proportional with a fixed offset, as can be expressed with the formula F = (9/5)C + 32.

Explanation:

The relationship between the Fahrenheit and Celsius temperature scales is neither inversely proportional, nor unrelated. Instead, the relationship is a combination of direct proportionality and a fixed offset.

More specifically, the Fahrenheit temperature scale is a linear transformation of the Celsius scale, being directly proportional to it but offset by a constant value.

This relationship can be expressed with the formula: F = (9/5)C + 32.
