Respuesta :

To find the slope of the line we have to identify two point in the line so I can see the coordinates: (-5, 3) and (5, -1), so now we can use the equation of the slope:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Now we replace the coordinates so:

[tex]\begin{gathered} m=\frac{-1-3}{5-(-5)} \\ m=-\frac{4}{10} \\ m=-\frac{2}{5}=-0.4 \end{gathered}[/tex]
