Essentially, if something is increasing or decreasing in a lineal fashion, it is doing so at a constant rate. This term is often contrasted with nonlinear relationships, where changes do not occur in a straight line.

Origin of 'lineally'
The term 'lineally' derives from the Latin word 'linealis', which means 'of or belonging to a line'. This Latin word is rooted in 'linea', meaning 'line' or 'string'. The evolution of the word into English reflected not just its geometric applications but also its metaphorical implications in various fields, including mathematics and philosophy. Historically, the term has been used to describe relationships in both a concrete spatial context and an abstract conceptual framework. It emphasizes continuity and direct connection, making it particularly valuable in scientific and technical discourses. Lineal relationships have been a foundational concept in mathematics, originating in ancient canons of geometry and progressing through the Renaissance and into modern calculus, where they helped define the principles of motion and change.
