The Line(u, v) command computes the equation of the line, its slope, and the y- and x-intercepts from the data specified by u and v.  These values are returned in the form of an expression sequence; therefore, Line(1,2)[1] will obtain the equation of the line with slope  and y-intercept .

* 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 or v is an algebraic expression and the other is either a list of 2 algebraic values or a 2-D Vector with algebraic components, the algebraic expression is the slope and the list or Vector specifies 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.

The optional parameters opts specify the desired output options for the resulting plot when output = plot. The available options are:

lineoptions = list

Specifies the plot options for the line.

output = value or plot

This options controls the return value of the function.

* output = value computes the equation of the line, its slope, and the y- and x-intercepts.  The default is output=value.

* output = plot displays a plot.  The data parameters u and v must be constant values when specifying this value.

pointoptions = list containing plot options for points on the line

Specifies the plot options for the points on the line.

title = string

Specifies the title to be displayed on the plot.

view = list

Specifies the x- and y-range of the plot.
