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).
Why are all horizontal lines parallel?
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.
What is the difference between undefined slope and no slope?
Undefined slope is when a line is exactly on the y-axis, for reasons unknown, the slope of a line on the y-axis cannot be determined, so therefore it it "undefined." A line with no slope is a line with a slope of zero. In order for a line to have a slope of zero, it must be directly on the x-axis, meaning it is horizontal. Horizontal lines are straight and have no slope
What is the slope of a line parallel to a line with slope -2?
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.
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
Lines always have a slope of zero.?
Horizontal lines always have a slope of zero. (i.e completely flat, level surfaces have a slope of zero). However a line does not have to have a slope of zero in order to be a line.
The slope of a horizontal line is?
Horizontal lines have a slope of 0.
What are Lines having no slope?
Lines with no slope are horizontal lines or flat lines
Do horizontal lines have an undefined slope?
No. The slope of a horizontal line is zero. The slope of a vertical line is undefined.
Do horizontal lines always have a slope of zero?
Yes. There is no positive or negative rise to generate a slope, and it cannot have a run of zero length.
Do vertical lines have a slpoe of zero?
No. Horizontal lines have zero slope. Vertical lines have infinite slope.
What type of slope does vertical lines have?
a slope of zero. horizontal is undefined
Do horizontal lines have a slope of 0?
Yes.
A vertical line has a run which is?
run as in slope of a line is zero . horizontal lines have no slope and vertical lines have a slope of zero
When is the product of the slope of two perpendicular lines not equal to -1?
When the lines are horizontal and vertical. (slope of zero) (undefined slope)
Do all horizontal lines have the same slope?
yes
What is the slope of a line that is parallel to a horizontal line?
Well since the lines are parallel they would have the same slope. And the slope of any horizontal line is 0. The slope of a vertical line is undefined.
