Important: The student package has been deprecated. Use the superseding command Student[Precalculus][Slope] instead.

The function slope will compute the slope of a line determined by two points, or by an equation.

If equation is of the form $y=f\left(x\right)$, then the dependent variable is taken to be y, and the independent variable to be x.  Ambiguity caused by three or more unknowns or by the use of a different form of equation is resolved by providing two additional arguments, y and x, the names of the dependent and independent variables, respectively.

The command with(student,slope) allows the use of the abbreviated form of this command.
