you use the formula!!!
Rise/Run
or (x2-x1)/(y2-y1)
eg: (2 3) (4 6)
(4-2)/(6-3)= 2/3!!!
If you have the equation Y=MX+B M=Slope of the line
The closer the contour lines the steeper the slope.
You have to know the slopes of both lines. -- Take the two slopes. -- The lines are perpendicular if (one slope) = -1/(the other slope), or the product of the slopes equals to -1.
The area with the steepest slope is the area where the contour lines are bunched closest together.
The steeper the slope, the contour lines go further along the area. You can also determine the flatness of the area with these lines.
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.
Lines with no slope are horizontal lines or flat lines
If the lines are straight and have the same slope they are parallel, no matter what the y intercept is
the lines tha determine you, consider and think about ones comment
Flatter lines have a _____ slope than that of steeper lines
Lines that have the same slope are said to be parallel lines.
Closely spaced contour lines mean that the slope is steep.
Horizontal lines always have a slope of 0.
