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.
An undefined slope is vertical.
A vertical line has an undefined slope.
A line with a slope of zero is a flat, vertical line.
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.
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.
a vertical line has an undefined slope, while a horizontal slope has a slope of zero.
Vertical. Te horizontal like has zero slope ( no slope) and the vertical line has infinite (very very high) slope
A vertical line HAS NO slope! The slope is undefined in this case.
An undefined slope is vertical.
The slope of a vertical line is not defined.
run as in slope of a line is zero . horizontal lines have no slope and vertical lines have a slope of zero
The slope of a line is undefined if the line is vertical.
