Linear Function   »      

With B you can set any slope
of the line g through the origin.
With you can move g as you like.

In general:

If a straight line with the slopem runs through
a point P(xP,yP), then its equation is
y - yP = m(x - xP) or y = m(x - xP) + yP

One denotes
y = m(x - xP) + yP
as the point-slope form of the straight line equation.
