1. Any function whose graph is a straight line: f(x)=ax+b

   lineare Funktion

   a mathematical function whose graph (in Cartesian coordinates with uniform scales) is a line in the plane.

2. Any function whose value on the sum of two elements is the sum of the values of the function on the two elements and whose value on the product of a scalar times an element is the scalar times the value of the function on the element: f(ax+by)=af(x)+bf(y)
