Scope note:

Inclined surfaces, slopes, or declivities; a slope is the numerical measure of a line’s inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it. Given a straight line in a plane, the constant value m=(y2-y1)/(x2-x1), where (x1, y1) and (x2, y2) are any two points on the line.
