The slope is 29
Explanation:The slope of a line is given as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Where -82 and -81 are the coordinates for x, and
-25 and 4 are the coordinates for y.
[tex]\begin{gathered} m=\frac{4-(-25)}{-81-(-82)} \\ \\ =\frac{4+25}{-81+82} \\ \\ =\frac{29}{1}=29 \end{gathered}[/tex]
