(B) The relationship between Celsius $(C)$ and Fahrenheit $(F)$ scales is given by the formula: $\frac{C}{5} = \frac{F - 32}{9}$ Rearranging this equation to the form $y = mx + c$ (where $y = C$ and $x = F$): $C = \frac{5}{9}F - \frac{160}{9}$ This is a linear equation of the form $y = mx + c$,where the slope $m = \frac{5}{9}$ is positive and the $y$-intercept $c = -\frac{160}{9}$ is negative. $A$ graph with a positive slope and a negative $y$-intercept corresponds to a line that passes through the fourth quadrant and has a positive inclination. Comparing this with the given options,Figure $B$ represents a line with a positive slope and a negative $y$-intercept.

Which of the following figures represents the relation between Celsius $(C)$ and Fahrenheit $(F)$ temperatures?
