The slope of a vertical line is undefined. Horizontal slope is 0.

a vertical line has an undefined slope, while a horizontal slope has a slope of zero.

A vertical line has an undefined slope.

vertical apex.

A line with no slope is a vertical line. The slope is undefined, and cannot be represented by a real number. A horizontal line has a slope, but the slope is zero. Consider the "y = mx + b" form of the straight line equation. For a horizontal line the slope is zero, so y = 0x +b => y = b, which is the equation of a horizontal line. For a vertical line, there is no slope, so you can't substitute for m; the equation can't be written in the form y = mx +b. The equation of a vertical line has the form x = a.
