First, we have to find the slope.


m=(y_2-y_1)/(x_2-x_1)

Let's replace the points (-10,-11) and (-8,-9).


m=(-9-(-11))/(-8-(-10))=(-9+11)/(-8+10)=(2)/(2)=1

Then, we use the point-slope formula to find the equation


\begin{gathered} y-y_1=m(x-x_1) \\ \end{gathered}

Let's replace the point (-8,-9) and the slope 1.


\begin{gathered} y-(-9)=1(x-(-8)) \\ y+9=x+8 \\ y=x+8-9 \\ y=x-1 \end{gathered}

Hence, the equation that represents the table is


y=x-1
