For each of the below, indicate if the curve in question would shift to the left, to the right, or not at all. Assume perfect competition, and that other than the change listed everything else remains the same (i.e. ceteris paribus).

How would the DEMAND CURVE shift if there was:

A decrease in income and the good is a normal good
