A linear function is a mathematical relationship between two variables, where the graph of the function forms a straight line. The relationship is defined by a constant ratio between the x and y values, indicating a constant rate of change. For instance, a linear function can be represented by the equation y = mx + b, where m is the slope (rate of change) and b is the y-intercept (starting point).
