slope

n. side of a hill, incline; upward or downward slant; degree to which a surface deviates from the vertical

v. incline, slant upward or downward; cause to tilt, slant

Slope is often used to describe the measurement of the steepness, incline, gradient, or grade of a straight line. A higher slope value indicates a steeper incline. The slope is defined as the ratio of the "rise" divided by the "run" between two points on a line, or in other words, the ratio of the altitude change to the horizontal distance between any two points on the line. It is also always the same thing as how many rises in one run.
