The slope formula is givenb by:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
To get the slope from the graph, we will pick out two points lying on the line:
Point 1: (x, y) = (-6, 10)
Point 2: (x, y) = (0, -8)
We will then proceed to use these points to calculate the slope, we have:
[tex]\begin{gathered} m=\frac{-8-10}{0--6}=-\frac{18}{6} \\ m=-3 \end{gathered}[/tex]
The slope (m) = -3
