WebJan 4, 2024 · Definition: Linear Function. A linear function is a function whose graph is a line. Linear functions can be written in the slope-intercept form of a line. f(x) = mx + b. where b is the initial or starting value of the function (when input, x = 0 ), and m is the constant rate of change, or slope of the function. The y-intercept is at (0, b). WebJan 13, 2024 · 9.
