Answer
There is an undefined slope.
Work Step by Step
Our two points are:
(-5, 0.124), (-5, -0.584)
The Slope Formula is: $\frac{y1−y2}{x1−x2}$
Lets plug our two points in to this slope formula to find the slope of these two points:
$\frac{0.124-(-0.584)}{-5-(-5)}$
=$\frac{0.708}{0}$
We cannot divide any number by zero so therefore this slope is undefined.
