The slope of a line is given by:
[tex]m=\frac{\Delta y}{\Delta x}[/tex]Choose two ordered pairs of values to find the slope. For instance, use (1,8) and (4,6).
Substitute these data into the equation for m:
[tex]\begin{gathered} m=\frac{8-6}{1-4} \\ =\frac{2}{-3} \\ =-\frac{2}{3} \end{gathered}[/tex]Therefore, the slope of the line is -2/3.
