$0$

The formula to find slope is:

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

Where $m$ is the slope

$(x_1,y_1)$ and $(x_2,y_2)$

Next plug in both set of parenthesis into the equation

$m=(5-5)/(-1-2)$

Solve numerator (top) and denominator (bottom)

$m=0/-3=0$

Because the slope is $0$ , the line is horizontal because it has all the same $y$ coordinate points
