Input the utility level you want to hold constant and click "Refresh". The calculator will display the Hicksian bundle in purple, the isocost line in blue, and the corresponding indifference curve in green.
A Note on Theory: The Tangency Condition and the Feasibility Condition
The graphical solution demonstrates that the Hicksian demand bundle satisfies:
1) The tangency condition: the isocost line and indifference curve are tangent at the Hicksian demand bundle — the slope of the isocost line (\frac{P_{x}}{P_{y}}, the price ratio) and the slope of the indifference curve (\frac{U_{x}}{U_{y}}, the marginal rate of substitution) are equal to each other
2) The feasibility condition: the Hicksian demand bundle lies on utility curve fixed at the level of utility specified
