Suppose that a consumer's income, I, and the price of good 2, $p_2$, each remain fixed.
What will happen to the budget line if the price of good 1, $p_1$, were to increase?
(Note: Assume, as usual, that good 1 is on the horizontal axis and good 2 is on the vertical axis)
The budget line will pivot outwards, with the same vertical intercept and a flatter slope.
The budget line will pivot inwards with the same horizontal intercept and a flatter slope.
The budget line will shift out parallel to the original budget line, with higher vertical and horizontal intercepts
The budget line will pivot inwards, with the same vertical intercept and a steeper slope.
