To find the slope through any pair of points, use this formula:
[tex]\boxed{\begin{gathered}\underline{\sf{Slope\;Formula}}\\\\\sf{m=\cfrac{y_2-y_1}{x_2-x_1}}\end{gathered}}[/tex]
Plug in the points:
[tex]\sf{m=\cfrac{4-(-9)}{2-(-2)}}[/tex]
[tex]\sf{m=\cfrac{4+9}{2+2}}[/tex]
[tex]\sf{m=\cfrac{13}{4}}[/tex]
Hence, M = 13/4.
