The budget constraint for a consumer who only buys apples (A) and bananas (B) is PAA + PBB = I where consumer income is I, the price of apples is PA, and the price of bananas is PB. To plot this budget constraint in a figure with apples on the horizontal axis, we should use a budget line represented by the slope-intercept equation:A.
A = -I/PA + (PB/PA)B
B.
A = I/PA - (PB/PA)B
C.
B = -I/PB + (PA/PB)A
D.
