Linear Function   »      

The quotient     4   =   2   =   2 
 2   1  
gives the slope m of the line.

In the equation of the function y = mx is
m the slope factor
or slope for short.

Each straight line is uniquely identified by a gradient triangle.

Move and you can
have any slope triangle drawn.

With B you can set any slope
of the straight line g.
