Rotations in Budget Line  2. Shifts in Budget Line.  To understand the concept, it is assumed that the quantity of Good-X is shown on the X-axis and the quantity of Good-Y is shown on Y-axis. 1. Change in Price/Rotations/Movements in Budget Line When there is a change in the price of only one good either Good-X or Good-Y, the budget line tends to rotate. The effect of change in price of a good is visible in four different ways mentioned below: a. Increase in Price of Good-X: When the price of Good-X increases leaving no change in the price of Good-Y, People would buy less of Good-X that would rotate the budget line from right to left towards X-axis i.e. from ab to ac in figure 1.1 causing the budget line to be steeper.                Figure 1.
