👉 In mathematics, a dyeline is a term used to describe the relationship between two or more different variables. It is often used in mathematical models and analysis to represent relationships between variables that are not directly proportional but have some sort of linear relationship. A dyeline can be defined as an equation that relates one variable to another based on its value at a specific point, such as when plotting a graph. The slope or gradient of the line connecting two points is often used to determine if the variables are related
