student[slope] - compute the slope of a line

Calling Sequence

slope(equation)

slope(equation, y, x)

slope(equation, y(x))

slope(p1, p2)

Parameters

equation

-

equation of a line

y, x

-

(optional in most cases) dependent and independent variables

p1, p2

-

two 2-D points (such as [a, b] and [c, d])

Description

• 

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=fx, 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.
