A horizontal line has a slope of zero. For a vertical line, the slope is not defined (change of y / change of x would result in a division by zero).

Closely spaced contour lines mean that the slope is steep.
Horizontal lines always have a slope of 0.
Yes, that's what makes them parallel lines - they have the same slope. So they never will intersect with each other. If a set of lines didn't have the same slope, at some point they would intersect and thus would not be parallel.
No. Horizontal lines have zero slope. Vertical lines have infinite slope.
run as in slope of a line is zero . horizontal lines have no slope and vertical lines have a slope of zero
When the lines are horizontal and vertical. (slope of zero) (undefined slope)
No but if the two lines are parallel then they will have the same slope.
Lines with the same slope but with different y intercepts are parallel.
If two lines are parallel and one has a slope of 1.3, what is the slope of the other line?
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.
How close together the brown contour lines are Yes, the closer the contours the steeper the slope. Flat land, by definition, has no contour lines.
