Answer:

Step-by-step explanation:
Equation of straight line in point slope form is given a s

Here



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).

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