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
