lin2: Linear function defined from two planar points (x1,y1) and (x2,y2)

Description

It gives the value of the linear function defined from two points (x1,y1) and (x2,y2) at any x

Usage

lin2(x1, y1, x2, y2, x)

Value

It returns the value of the linear function from (x1,y1) to (x2,y2) at an arbitrary x.

Arguments

x1

the x - abscissa of the first point

y1

the y - ordinate of the first point

x2

the x - abscissa of the second point

y2

the y - ordinate of the second point

x

the x - point where we compute the value of the linear function
