An inclined surface usually defined by the ratio of the horizontal distance to the vertical distance, i.e. 2:1 (2 horizontal units to 1 vertical unit). Change in elevation per unit of horizontal distance. Side of a hill or a mountain. The inclined face of a cut, canal, or embankment. Inclination from the horizontal. Expressed in percent when the slope is gentle; in this case also termed gradient. Degree of deviation of a surface from the horizontal, usually expressed in percent or degrees. Sometimes referred to as batter when measured from vertical.

The side of a hill or mountain, the inclined face of a cutting, canal or embankment or other inclination from the horizontal. In the United States, it is measured as the ratio of the number of units of horizontal distance to the number of corresponding units of vertical distance. The term is expressed as a percent when the slope is gentle, in which case the term "gradient" is also used.

A measure of change in surface value over distance, expressed in degrees or as a percentage. For example, a rise of 2 meters over a distance of 100 meters describes a 2% slope with an angle of 1.15. Mathematically, slope is referred to as the first derivative of the surface.

Telecommunications

In a transmission line, the rate of change of attenuation with respect to frequency over the frequency spectrum. Note 1: The slope is usually expressed in dB per hertz or dB per octave. Note 2: In metallic lines, the slope is usually greater at high frequencies than at low frequencies.
