To find the slope of the line between two points, we use the equation
[tex]m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } [/tex]
Where m is the slope of the line. Now, we substitute our given values into the equation, and solve for m:
[tex]m = \frac{ (- 9) - ( - 5)}{(9) - ( - 5)} [/tex]
[tex]m = \frac{ - 9 + 5}{9 + 5} = \frac{ - 4}{14} = \frac { - 2}{7} [/tex]
So, the slope of the line is - 2/7
