👉 In mathematics, a lineal is a term that refers to a linear function. A linear function is a function of the form f(x) = ax + b, where 'a' and 'b' are constants and x is an input variable. A lineal can be defined as a set of points on a plane, each having a corresponding value for its independent variable (x), which in turn gives a corresponding value for its dependent variable (y). This concept allows us to describe the behavior
