Slopemathematicalematical concept. For a line, slope is computed by "rise over run," or the change in the y position divided by the change in the x position for the Cartesian coordinate system. The standard equation of a line y = mx + b gives a line with a slope of m. For geometric objects other than lines, things become a bit more complicated; they require the calculus concept of a derivative. For a function f in x, the slope at a particular point x along the x axis is defined to be the derivative of f with respect to x (df/dx, or simply f'(x)).
