@sammmy3079: A linear function is a first-degree polynomial function. When plotted on a coordinate plane, it forms a perfectly straight line. It shows a relationship where any change in the independent variable leads to a strictly proportional and constant change in the dependent variable [1]. Because of this predictable and unchanging behavior, linear functions are fundamental to algebra, calculus, and real-world predictive modeling. #Mbappespecial #math #xyzbca #pleasegoviral #funny
