Meaning of Budget Set:-

It refers to attainable combinations of a set of goods, given prices of goods and income of the consumer. The budget set equation can be written as:

P₁X₁+P₂X₂≤ Y

Here,

P₁ refers to the price of Good-1

X₁refers to the quantity of Good-1

P₂refers to the price of Good-2

X₂ refers to the quantity of Good-2

Y refers to total expenditure or total budget.

Relationship with Income	The sets of two goods and their prices always fall under or equal to the total budget of the consumer.	Here, the bundles of two goods and their prices are always equal to the budget of the consumer.
Inter-Relationship	It provides a basis to represent the budget line.	It comprises a different combination of two goods in a budget set.
Also known as	It is also known as the Opportunity set.	It is also known as Budget Constraint or Price Line.
Graphical Representation	The consumption sets that lie under and on the budget line form the budget set.	The consumption sets that lie on the budget constraint itself form the budget line.

Conclusion:

Thus, the Budget set provides all attainable combinations of two goods for all combinations of income and prices of commodities to make a budget line. Both terms are important to find out the consumer equilibrium point through indifference curve analysis.
