A line that is at right angles to a vertical line is said to be horizontal.
The slope of a vertical line is undefined. Horizontal slope is 0.
A vertical line.
The y axis on the Cartesian plane is a vertical number line
The slope of a vertical line would be parallel to the y axis.
WHY THE LINE X=4 IS A VERTICAL LINE.
yes
x=4
Because X (which in this case is always 4) is the value of the horizontal axis so the only value that can change is Y, the verticle axis.
x = 4 is the set of all points where the x coordinate = 4 On a number line, it's easy to graph. You simply place a dot on the number 4. When you extend that number line along the y axis, the dot extends, as well, into a line.
A vertical line!
A horizontal line is perpendicular to 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?
A blinking vertical line is a cursor.
