Calling Sequence

LinearFunction(t)

LinearFunction(p1, p2))

Parameters

t

-

linear expression in one variable or linear equation in variables x and y

p1, p2

-

a GridPoint object or list/rtable with two values representing a point on the line

Options

• 

domain : a RealRange expression specifying the region over which the line is defined

• 

variable : name used in generated expression if the second calling sequence is used

Description

• 

The LinearFunction constructor generates and returns a line object.

• 

If the equation form is given, the variables must consist of x and/or y only. The equation is converted to the form y=fx and only the right-hand-side is saved within the object.

• 

Vertical lines can also be constructed using two points with the same x-value or an expression of the form x=a where a is a constant. In this case, the equation x=a is returned if the Grading:-GetExpression command is called.
