Answer
The slope of the line is $0$.
Work Step by Step
Take first two points from the table.
$(x1,y1)=(-4,-1)$ and $(x2,y2)=(-3,-1)$.
Use slope formula.
$\Rightarrow m=\frac{y2−y1}{x2−x1}$
Substitute all the values.
$\Rightarrow m=\frac{-1−(-1)}{-3−(-4)}$
Simplify.
$\Rightarrow m=\frac{-1+1}{-3+4}$
$\Rightarrow m=\frac{0}{1}$
$\Rightarrow m=0$
Hence, the slope of the line is $0$.
