## Calculus 8th Edition

(a) The image of the graph has been added. (b) The slope of the graph is $\frac{9}{5}$. It represents the rate of change of $F$ with respect to $C$; for example, if $C$ changes by unit, then $F$ changes by $\frac{9}{5}$. The $F$-intercept of of the graph is $32$. It represents the value of $F$ for $C=0$.
(a) It has been explained in the answer. (b) The general form of a line is $y=mx+d$, where $m$ is the slope and $d$ is the $y$-intercept of the graph.
