Let's find the slope (m), considering the two points (9 , -1) and (4 , -11) ~
[tex] \boxed{ \boxed{\sf\dfrac{y_2 - y_1}{x_2 -x_1 }}}[/tex]
[tex]{ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{ - 1 - ( - 11)}{9 - 4} [/tex]
[tex]{ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{ - 1 + 11}{5} [/tex]
[tex]{ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{ 10}{5} [/tex]
[tex]{ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:2[/tex]
Therefore, the slope of line passing through given points is ~ 2
