To find the slope(m) of the line, you use the slope formula:
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
And you plug in the points into the equation.
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m = \frac{-72-(-9)}{-9-0}[/tex]
[tex]m = \frac{-72+9}{-9-0}[/tex]
[tex]m = \frac{-63}{-9}[/tex]
m = 7
