The LineTutor(f) command launches a tutor interface that illustrates the various forms of the equation of the line specified by f.

If f is not specified, LineTutor uses a default function.

The LineTutor(u,v) command launches the tutor interface initialized by the line defined by the data specified in the parameters.

* If u and v are both algebraic expressions, then u is taken as the slope and v as the y-intercept of the line.

* If one of u and v is an algebraic expressions and the other is either a list of 2 algebraic values or a 2-D Vector with algebraic components, then the algebraic value is taken as the slope and the list or Vector as a point on the line.

* If u and v are both 2-element lists or 2-D Vectors with algebraic components, then they are taken as points on the line. In this case, u and v must specify different points.
