d = run Δh = rise l = slope length α = angle of inclination. The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates ...
Slope: = = In mathematics, the slope or gradient of a line is a number that describes the direction of the line on a plane. [1] Often denoted by the letter m, slope is calculated as the ratio of the vertical change to the horizontal change ("rise over run") between two distinct points on the line, giving the same number for any choice of points.
The seked is proportional to the reciprocal of our modern measure of slope or gradient, and to the cotangent of the angle of elevation. [2] Specifically, if s is the seked, m the slope (rise over run), and the angle of elevation from horizontal, then: = = ().
The slope of a nonvertical line is a number that measures how steeply the line is slanted (rise-over-run). If the line is the graph of the linear function f ( x ) = a x + b {\displaystyle f(x)=ax+b} , this slope is given by the constant a .

Therefore, it would be useful to make this equation written as a function of both and, to be able to draw lines at any angle. The angle (or slope) of a line can be stated as "rise over run", or /. Then, using algebraic manipulation,
