A vertical line goes up and down otherwise to say it goes straight up
A horizontal line is perpendicular to a vertical line.
In a pedigree, a vertical line and a bracket connect _____.
A vertical line goes North And South and a horizontal line goes East And West.
=== === A vertical line is a line with an undefined slope. Note that this is different from an infinite slope. The slope of a vertical line is said to be undefined. It may be said to go "straight up and down"A vertical line is drawn on a graph by plotting x = nwhere n equals any real number. The value of n is located on the x axis and then a line is drawn parallel to the yaxis through that x value. Note that the y axis itself is a vertical line. There are an infinite number of possible lines with an undefined slope, of course. Any number on the x axis can have a line drawn through it parallel to the y axis, and any one of those lines is said to be a vertical, and will have a slope that is undefined.A simpler definition say a vertical a line is a line that goes up to down
A vertical edge is A line that go straight up and down
A vertical line goes up and down otherwise to say it goes straight up
Vertical lines go up and down. Horizontal lines go left to right.
up and down
Up and down!!!!!
i think the horizontal is the line go up and vertical is the line go straight across
A vertical line!
A horizontal line is perpendicular to a vertical line.
WHY THE LINE X=4 IS 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 horizontal line is a line perpendicular to the vertical.
all vertical lines are parallel to waht type of line?
