Any line y=m is horizontal. The y-coordinate of any point lying on such line is m, only x-coordinates change.

If y=1, then two points on the line are (x₁,1) and (x₂,1).

$\hbox{the slope: } m=\frac{y_2-y_1}{x_2-x_1}=\frac{1-1}{x_2-x_1}=\frac{0}{x_2-x_1}=0$

So, the slope of this and any horizontal line is 0.

The answer is a.
