By definition, lines are parallel if they have the same gradient (slope). Any horizontal line has a gradient of 0, so it is parallel to any other horizontal line.

If the slope of a line is zero What is the slope of the line that is parallel to it?
The parallel line would also have a slope of zero (both are horizontal lines).
What is the definition of a slope of parallel lines?
Horizontal lines have a slope of zero, and the slope of vertical lines is undefined. Parallel lines have equal slopes, and perpendicular lines have slopes that are negative reciprocals of each other. So we can say that: Two nonvertical lines are parallel if and only if they have the same slope. Two lines are perpendicular if and only if their slopes are negative reciprocals of each other. That is, if the slopes are m1 and m2, then: m1 = - 1/m2 or (m1)(m2) = -1
How do you add 5 lines to 6 parallel lines to make a total of 9?
Meaningless question. It sounds like a riddle rather than a maths problem. For an answer, assuming it is a riddle, I'd look at the letters that spell NINE. The six parallel lines are the vertical strokes of the letters; the extra five lines are the horizontal and diagonal strokes.
What slope do horizontal lines always have?
Horizontal lines always have a slope of 0.
How many parallel lines does a cone have?
A cone does not have any parallel lines
What are all horizontal lines parallel to?
other horizontal lines? which would be 180 degrees i guess.
Do horizontal lines intersect?
No, horizontal lines are parallel to each other and parallel lines never intersect.
Draw parallel horizontal lines?
Parallel lines are lines that, if extended, would never intersect with eachother. This means that they are going in the same direction, eg. | |, but not | \. Horizontal means that that are going across, eg. ___________________, not |. An example of a lines that are parallel and horizontal: _____________________________________ _____________________________________
Are all horizontal lines parallel?
Yes, as long as each line is different.
What is parallel or lines of latitude location?
They are the horizontal lines on a map.
Why is a horizontal lines called horizontal?
because they are parallel to the plane of the horizon
Are lines of latitude perpendicular parallel or intersecting?
Lines of latitude are horizontal and run parallel to the poles
How many horizontal lines are in the letter Z?
There are 2 horizontal parallel lines in the letter Z
What is horizontal markings?
Horizontal markings are markings (such as painted or etched lines) that are horizontal (or parallel to the ground).
What way does a horizontal line go?
A horizontal line goes from left to right and looks like this. Also, all horizontal lines are parallel to each other. ______________________________________________________________________ ______________________________________________________________________
What do parallel horizontal lines look like?
Like this: _______________________________ _______________________________ _______________________________
Does D have parallel lines?
No but it does have an horizontal line of symmetry
