    Which of the curves in figure represents the relation between Celsius and Fahrenheit temperatures

    A)            1

    B)            2

    C)            3

    D)            4

    Correct Answer: A

    Solution :

               \[\frac{C}{5}=\frac{F-32}{9}\]Þ\[C=\left( \frac{5}{9.} \right)\,F-\frac{20}{3}.\] Hence graph between °C and °F will be a straight line with positive slope and negative intercept.
