Question

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

• A. a
• B. b
• C. c
• D. d

Answer 1

The correct option is A a

We know that,

$\frac{C}{5}=\frac{F-32}{9}$

$C=\left(\frac{5}{9}\right)F-\frac{20}{3}$

Hence, graph between ${}^{0}C$ and ${}^{0}F$ will be a straight line with positive slope and negative intercept.

So the correct answer is option A.
