(A) The relationship between Celsius $(C)$ and Fahrenheit $(F)$ temperatures 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{32 	imes 5}{9}$$C = \frac{5}{9}F - \frac{160}{9}$$C = \frac{5}{9}F - 17.78$This equation represents a straight line with a positive slope $(m = \frac{5}{9})$ and a negative $y$-intercept $(c = -17.78)$.Looking at the provided figure,curve $1$ is the only line that has a positive slope and passes through the negative $C$-axis (negative intercept).Therefore,curve $1$ represents the correct relationship.

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