Vedclass · Answer

(B) The relationship between Celsius $(C)$ and Fahrenheit $(F)$ scales is given by the formula: $C = \frac{5}{9}(F - 32)$.This can be rewritten as: $C = \frac{5}{9}F - \frac{160}{9}$.Comparing this with the equation of a straight line $y = mx + c$,where $y$ is the temperature in Celsius and $x$ is the temperature in Fahrenheit,the slope $m$ is the coefficient of $F$.Therefore,the slope $m = \frac{5}{9}$.Alternatively,using the coordinates of points $A$ and $B$ from the graph:Point $A$ is $(32, 0)$ and point $B$ is $(212, 100)$.Slope $m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{100 - 0}{212 - 32} = \frac{100}{180} = \frac{5}{9}$.
