The graph of a linear function

$\displaystyle f(x) = ax+b$

is a straight line with slope

and

-intercept

$\includegraphics{lineare_funktion}$

Alternative representations are the point-slope form

$\displaystyle \frac{y-y_0}{x-x_0} = a$

and the two-point form

$\displaystyle \frac{y-y_0}{x-x_0} = \frac{y_1-y_0}{x_1-x_0}\,,$

where

and

are points on the straight line.
