If you mean a topographic map, then you just divide the distance between two contour lines by the change in height between the two points
first you put the cone on a graph and if you know how to find slpoe rise/runlay it flatif you do not know how to get slope check out my other answer on how to get slope
Parallel lines have the same slope. So if you know the slope of a line in question, or you can calculate it, then you know the slope of any line parallel to that line.
the slope is -5/4
y=mx+b whatever multiplies x in this form is the slope
No. If you have more than two points for a linear function any two points can be used to find the slope.
On a map they would indicate a steep slope And on a synoptic chart they would indicate stronger winds the closer they are. Depends on the differences in barometric pressure between the isobars.
Steep slope is indicated by topo lines close together.
The average slope is the ratio of the change between two points
a steep slope in geography is if you see one on a map then it would be lines that are close together,
Each contour line represents a rise in height (elevation). The closer the contour lines are on the map, the steeper is the slope.
If the contour lines are far apart, then that indicates the land has a gentle slope (low slope).
elevation. the closer the lines the steeper the slope.

If the topographic lines are closer together it means that it has a steeper slope grade, if they are farther apart, it means that they have a more relaxed slope grade. There is usually a scale on the map that can tell you in exact measurements of the slope.
The slope can be a fraction.
