What Are Linear Functions?
Linear functions are mathematical relationships where the highest power of the variable (typically x) is 1, making them first-degree polynomials. They graph as straight lines on a coordinate plane, following the form y = mx + b, where m is the slope and b is the y-intercept. These functions describe constant rates of change, making them essential for modeling real-world phenomena like distance over time or cost calculations. Linear functions are foundational in algebra and widely applied in various fields, from economics to physics.
