Answer :
Here's the solution :
we know,
[tex] \boxed{slope = \frac{y_2 - y_1 }{x_2-x_1} }[/tex]
where,
- [tex] y_2 = -10 [/tex]
- [tex] y_1 = -8 [/tex]
- [tex] x_2 = -9 [/tex]
- [tex] x_1 = 1 [/tex]
lets solve,
- [tex] \hookrightarrow \dfrac{ - 10 - ( - 8)}{ - 9 - 1} [/tex]
- [tex] \hookrightarrow \dfrac{ - 2}{ - 10} [/tex]
- [tex] \hookrightarrow \dfrac{1}{5} [/tex]
