  • How to Solve Linear Functions | Study

    The equation for a linear function is: y = mx + b, Where: m = the slope, x = the input variable (the "x" always has an exponent of 1, so these functions are always first degree polynomial.). b = where the line intersects the y-axis. The equation, written in this way, is called the slope-intercept form. Examples of linear functions: f(x) = x,
