On the standard Cartesian graph, horizontal lines have zero slope. They all have the equation Y = a number
The lines all have the same slope.
The straight line equation is y = mx + b. If they do not cross and have the same slope they are parallel; if they cross and the slope (m) of one of them is the negative inverse slope of the other (-1/m) they are perpendicular. Otherwise they are neither
All parallel lines have a zero slope.
A vertical line has an undefined slope. If a line is vertical, the horizontal coordinate, commonly known as the x coordinates, must all be the same. If not, the line would not be vertical.
