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.
It is a parallel or a colinear line
It has no slope and is parallel to the x axis
A line with a slope of 0 would be perfectly horizontal or parallel with the x-axis.
A horizontal line parallel to x axis (slope = 0)
Slope = zero. The line is horizontal, parallel to the x-axis.
The parallel line would also have a slope of zero (both are horizontal lines).
It is a parallel or a colinear line
The line y = 6 is horizontal and has a slope of zero, as does any line that is parallel to it.
It has no slope and is parallel to the x axis
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.
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'.
the x-axis is the horizontal line which means the slope is 0. any line parallel also has a slope of zero
A line with a slope of 0 would be perfectly horizontal or parallel with the x-axis.
A horizontal line parallel to x axis (slope = 0)
Slope = zero. The line is horizontal, parallel to the x-axis.
the slope of the line y=3 is 0. if you draw the line y=3, you get a straight horizontal line across the 3 on the y axis. Since the line is horizontal and parallel to the x axis, it's slope is 0.
That means the line is horizontal. It runs parallel to the X axis.
