2)
the given points are,
[tex]\begin{gathered} (x_1,y_1)=(2,2) \\ (x_2,y_2)=(4,1) \end{gathered}[/tex]
The formula to find the slope of the graph is,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
thus, plug in the points respectively,
[tex]\begin{gathered} m=\frac{1-2}{4-2} \\ m=\frac{-1}{2} \\ m=-\frac{1}{2} \end{gathered}[/tex]
The slope of the given graph is -1/2.
