    Find the slope using the following points:

        (20, -10) (6, -20)

$\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}$

Use the slope formula:-

                    $\LARGE\text{ \displaystyle\frac{y_2-y_1}{x_2-x_1} }$

Replace letters with numbers as follows:-

                             $\Large\text{ \displaystyle\frac{-20-(-10)}{6-20} }$

On simplification,

                                  $\Large\text{ \displaystyle\frac{-20+10}{-14} }$

On further simplification,

                                        $\Large\text{ \displaystyle\frac{-10}{-14} }$

Reducing the fraction,

                               $\large\text{ \displaystyle\frac{10}{14} }$

               $\large\text{ \displaystyle\frac{5}{7} }\leftarrow\:slope$

Good luck with your studies.
