Parallel lines have the same slope.
It is a line parallel to the x or y axes that has no slope.
The line y = 6 is horizontal and has a slope of zero, as does any line that is parallel to it.
The slope of both lines will be the same.
=== === 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
For two lines to be parallel they must have the same slope. A line parallel to a line with slope -2 would have a slope of -2.
Parallel lines have the same slope. So if you know the slope of a line in question, or you can calculate it, then you know the slope of any line parallel to that line.
Parallel lines have the same slope. So if you have a line with slope = 2, for example, and another line is parallel to the first line, it will also have slope = 2.
Parallel lines have the same slope. The slope of the second line is also 13.
if the slope of a line is 2/3, then the slope of a parallel line would be 2/3.
The same. Parallel lines have the same slope.
2. Parallel lines have the same slope.
The slope is rise over run. If another line was parallel, the slope would be the same.
The parallel line would also have a slope of zero (both are horizontal lines).
It is also zero as parallel lines have the same slope
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.
Calculate the slope of the given line. Any line parallel to it will have the same slope.
