The line y = 6 is horizontal and has a slope of zero, as does any line that is parallel to it.
An horizontal line . A line parallel with the x-axis. NB A vertical line / a slope parallel with the y-axis is described as 'undefined'.
They will remain horizontal lines. A line parallel to the x-axis will remain a line parallel to the x-axis no matter how far back into space they go.
Perpendicular is when a line is at a right angle to another. Parallel lines are side by side and even if they were to go on to infinity, would never meet. Therefore the answer is perpendicular.
If the lines are in the same plane and never intersect they are always parallel. Two line can not intersect and be parallel if they are in different planes though. Take a cube for example, if you have one Sid of it and take the edge and then go to the opposite side and make a horizontal line they will never intersect but are also not 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.
A horizontal line is a line that is parallel to the horizon.
It is a parallel or a colinear 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.
Yes, it is. Think of the horizon. A horizontal line is parallel to the horizon.
No but it does have an horizontal line of symmetry
The parallel line would also have a slope of zero (both are horizontal lines).
The line y = 6 is horizontal and has a slope of zero, as does any line that is parallel to it.
It's a line segment that's parallel to the horizon.
An horizontal line . A line parallel with the x-axis. NB A vertical line / a slope parallel with the y-axis is described as 'undefined'.
When the line of an image on the two parallel horizontal sides are even, i.e. straight.
A horizontal line goes from left to right and looks like this. Also, all horizontal lines are parallel to each other. ______________________________________________________________________ ______________________________________________________________________
