This document discusses budget lines, consumer equilibrium, and price consumption curves. It defines a budget line as representing alternative combinations of two goods given money and prices. Consumer equilibrium occurs where the indifference curve is tangent to the budget line, maximizing utility subject to the budget constraint. A price consumption curve graphs how consumption choices change when the price of one good changes, by connecting points where the budget line touches the highest indifference curve. Various types of price consumption curves are defined such as backward sloping, upward sloping, varying slope, and horizontal.

2. Budget line :- It is a line which represent the alternative
combination of two goods with the given money and price of
two goods.

3. Equations of budget line:-
E= Qx.Px + Qy.Py
Slope of budget line:-
Px/Py or Py/Px
Budget constraint:-
Px.Qx + Py.Qy ≤ E

Y

4. Change of budget line :-
• Money income ( shift)
• Price of good X
• Price of good Y
Rotation

5. Consumer equilibrium:- A consumer shall be in equilibrium where
he can maximum his utility, subject to his budget constraint (OR)
where the indifference curve and the budget line are
constraint to each other the consumer is attained its Equilibrium.
E is equilibrium point having combinations of X
& Y. Any point C,D,F,G etc. cannot be considered
be optimum point because it lies on a lower
indifference curve than I 3

6. PRICE CONSUMPTION CURVE
Price-consumption curve is a
graph that shows how a
consumer’s consumption
choices change when price of
one of the goods changes. It is
plotted by connecting the
points at which budget line
touches the relevant
maximum-utility indifference
curve.
