TRUE/FALSE/EXPLAIN

1)If the price-consumption curve is upward sloping when the price of the good measured on the horizontal axis changes, then the demand curve for that good will be upward sloping.

Answer: False. An upward-sloping price-consumption curve indicates that as the price of the good falls, more of both goods will be purchased. So, the demand curve for the good measured on the horizontal axis slopes downward.
