Answer
The slope of the line is undefined.
Work Step by Step
Take first two points from the table.
$(x1,y1)=(3,-5)$ and $(x2,y2)=(3,-2)$.
Use slope formula.
$\Rightarrow m=\frac{y2−y1}{x2−x1}$
Substitute all the values.
$\Rightarrow m=\frac{-2−(-5)}{3−3}$
Simplify.
$\Rightarrow m=\frac{-2+5}{0}$
$\Rightarrow m=\frac{3}{0}$
Division by zero is undefined.
Hence, the slope of the line is undefined.
