If income effect for good X is negative, income consumption curve will slope backward to the left as ICC in fig 8.31. The substitution effect is the change that would occur if the consumer were required to remain on the original indifference curve; this is the move from A to B. The ICC obtained by joining optimal consumption combinations such as e, and e 1, in Figure.3 is a vertical straight line. .
