Answer
$slope=\frac{9}{5}$
Work Step by Step
To calculate the slope between points $(x_1,y_1)$ and $(x_2,y_2)$, we use the formula:
$slope=m=\frac{y_2-y_1}{x_2-x_1}$
We use the two points from Exercise 98, $(0,32)$ and $(100,\ 212)$:
$slope=\displaystyle \frac{212-32}{100-0}=\frac{180}{100}=\frac{9}{5}$
