Slope illustrated for y = (3/2)x − 1.Click on to enlarge Slope of a line in coordinates system, from f(x) = −12x + 2 to f(x) = 12x + 2. The slope of a line in the plane containing the x and y axes is generally represented by the letter m, [5] and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.
A flat or very gently sloping area on the floor of a deep ocean basin. absolute dating The process of determining a specific date (in years or some other unit of time) for an archaeological, geological or paleontological site or artifact. accident A sudden discontinuity of ground, such as a fault of great thickness, bed or lentil of unstable ...
Also datum level or datum line. The zero-elevation baseline or vertical datum to which a measurement of elevation or altitude is relative, e.g. the mean sea level calculated for a given location over a given period of time. [4] See also geodetic datum. de facto segregation The spatial and social separation of populations that occurs without ...
Cuesta – Hill or ridge with a gentle slope on one side and a steep slope on the other; Dissected plateau – Plateaus area that has been severely eroded so that the relief is sharp; Erg – Broad area of desert covered with wind-swept sand; Etchplain – Plain where the bedrock has been subject to considerable subsurface weathering
Informally, any sloping line is called diagonal. The word diagonal derives from the ancient Greek διαγώνιος diagonios, [1] "from corner to corner" (from διά- dia-, "through", "across" and γωνία gonia, "corner", related to gony "knee"); it was used by both Strabo [2] and Euclid [3] to refer to a line connecting two vertices of a ...
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 is either the elevation angle of that surface to the horizontal or its tangent. It is a special case of the slope, where zero indicates horizontality. A ...
In the U.S., the biggest polluters are often concentrated in underserved, mostly minority communities.
Slope or gradient of a line describes its steepness, incline, or grade, in mathematics. Slope may also refer to: Slope landform, a type of landform; Grade (slope) of a topographic feature or constructed element; Piste, a marked track for snow skiing or snowboarding; Roof pitch, a steepness of a roof; Slope, a 2007 album by Steve Jansen
