I will assume that we are trying to find the slope between (2,-6) and (-9,-6)
The slope's equation ⇒ [tex]\frac{y2-y1}{x2-x1}[/tex]
Let's set the variables:
(x1, y1) --> (2, -6)
(x2, y2) --> (-9, -6)
Now let's plug them in:
[tex]Slope = \frac{-6--6}{-9-2} =\frac{0}{-11} =0[/tex]
Thus the slope of the line is 0.
Hope that helps!
