Answer:
The final answer is D.
Explanation:
y=mx+b
where in this case
C=5/9
(F−32)
or
C=5/9 F− 5/9 (32)
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.
C=5/9 (F)
1=5/9 (F)
(F)=9/5
Since 9/5 = 1.8, statement II is true.
The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of 5/9 degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:
C=5/9 (F)
C=59 (5/9)
C= 25/81 (which is≠1)
An increase of 5/9 degree Fahrenheit leads to an increase of 25/81, not 1 degree, Celsius, and so Statement III is not true.
