Question

C=
5
9
(F−32)

The equation above shows how temperature F, measured in degrees Fahrenheit, relates to a temperature C, measured in degrees Celsius. Based on the equation, which of the following must be true?

A temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of
5
9
degree Celsius.
A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.
A temperature increase of
5
9
degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.
A) I only
B) II only
C) III only
D) I and II only

Answer 1

Answer:

You can see the slope of the graph is  

5 /9  , which means that for an increase of 1 degree Fahrenheit, the increase is  5 / 9  of 1 degree Celsius.

C= 5/ 9 (F)

C= 5/ 9 (1) = 5/ 9

Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of  9 /5  degrees Fahrenheit.

The final answer is D.    D) I and II only
