recall that to get the slope, all you need is two points.
so say, let's pick from the table hmmmmmmm (-3,6) and (1, -2).
[tex]\bf (\stackrel{x_1}{-3}~,~\stackrel{y_1}{6})\qquad
(\stackrel{x_2}{1}~,~\stackrel{y_2}{-2})
\\\\\\
slope = m\implies
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-2-6}{1-(-3)}\implies \cfrac{-2-6}{1+3}\implies \cfrac{-8}{4}\implies -2[/tex]
