What is what does linear mean?

Linear refers to a straight line or a sequence of events or actions that follow a predictable and constant pattern. In mathematics, a linear function has a constant rate of change and can be graphed as a straight line. In physics, linear motion refers to motion in a straight line, while nonlinear motion refers to motion with changing direction or velocity. In literature or storytelling, a linear narrative follows a chronological order of events. In computer programming, linear code is characterized by sequential instruction execution from the first line of code to the last.
