A vertical line has a slope of infinity.
The slope of a vertical line is undefined. Horizontal slope is 0.
A line with slope of zero is horizontal. A line with no slope is vertical because slope is undefined on a vertical line.
A vertical line has an undefined slope. For the line to be parallel to a vertical line, the slopes would have to be the same. Therefore, the line parallel to a vertical line also has an undefined slope.
The slope of a line becomes extremely large in magnitude as the line approaches being vertical;and is undefined or infinite for a truly vertical line.
Vertical. Te horizontal like has zero slope ( no slope) and the vertical line has infinite (very very high) slope
The slope of a vertical line is not defined.
An undefined slope is vertical.
The slope of a line is undefined if the line is vertical.
There is no slope defined for a vertical line.
yes it has no slope
