Price Elasticity of Supply - Graphical Representation

Graphical Representation

It is important to note that elasticity and slope are, in the most part, unrelated. Thus, when supply is represented linearly, regardless of the slope of the supply line, the coefficient of elasticity of any linear supply curve that passes through the origin is 1 (unit elastic). The coefficient of elasticity of any linear supply curve that cuts the y-axis is greater than 1 (elastic), and the coefficient of elasticity of any linear supply curve that cuts the x-axis is less than 1 (inelastic). Likewise, for any given supply curve, it is likely that PES will vary along the curve.
