A vertical line has an undefined slope. For the line to be parallel to a vertical line, the slopes would have to be the same. Therefore, the line parallel to a vertical line also has an undefined slope.
As long as they are not parallel, they will meet at an "edge", which is just a straight line .
Calculate the slope of the given line. Any line parallel to it will have the same slope.
Each line can either intersect the edge which is common to the two planes at some point or be parallel to it. If the two lines intersect the edge, but at different points, then the lines are skew. If only one of the lines intersects the edge, then again the lines are skew. If neither of them intersect, then the two lines are parallel to the same edge and so they are parallel to one another so not skew.
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.

No. Consider two adjacent faces on a cuboid. Both planes are parallel to the edge at which the intersect. But the fact that they do intersect illustrates that they are not parallel.
Parallel Lines. If they are in different planes, they need not be parallel. Think of a cuboid room. Line 1 is the edge formed by the floor and the wall opposite you. Line 2 is the edge formed by the wall behind you and the wall to your right. These two lines will not meet but they are certainly not parallel.

The same. Parallel lines have the same slope.
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.
The parallel line would also have a slope of zero (both are horizontal lines).
For making a clean edge with a straight line to it.
if the slope of a line is 2/3, then the slope of a parallel line would be 2/3.
since one parallel lines is perpendicular to another line, the other parallel line is perpendicular to the line as well. so the two would not be parallel, only the original two.
y = 3x+5 is parallel to y = 3x+7
