Application of linear functions in Economics (or) Application of straight lines in Economics The linear function is one in which ‘y’ is the first degree expression in ‘x’‚ i.e.‚ y = ax + b. The graph of this function is a straight line. The co-efficient of x represents the slope of the line. If a > 0‚ then the lines are upward sloping‚ and if a < 0‚ then the lines are downward sloping Let us explain certain linear equations used in Economics and business. 1. Linear cost curves
