Given a graph.
let us consider points,
[tex]\begin{gathered} (4,0) \\ (0,-2) \end{gathered}[/tex]The formula to find the slope m is,
[tex]m=\frac{y_2-y_1_{}}{x_2-x_1}[/tex][tex]\begin{gathered} m=\frac{-2-0}{0-4} \\ m=\frac{-2}{-4} \\ m=\frac{1}{2} \end{gathered}[/tex]The slope of the given graph is 1/2.
