D.-2

someone plz help me I would really appreciate it

Answer 1

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).

`\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`
