why does demand curve slopes downward from left to right for 6m

Dear student Downward slope of demand curve indicates the negative relationship between quantity demanded of the good and the price. The following are some of the factors responsible for the downward slope of demand curve. 1. Law of diminishing marginal utility - As per this principle marginal utility from each additional unit declines. When the more of units are consumed there will be fall in price. As a result consumer will tend to demand more when the price will be less. 2. Income effect - this explains that with the fall in price the real income of consumers tend to increase. With the rise in income consumers demand more of the goods when the prices are less. 3. Substitution effect - if the price of the commodity increases and the substitute product of the same is available at lower price consumer will tend to buy the substitute product which will decline the demand of other one and as a result demand curve slope download. 4. Large size of consumer group - as the consumer group is large in size and the the demand with respect to the same will also be bigger as a result prices will decline. 5. Different uses - if the commodity will have different uses consumer will by the same product which will cost him the less as a result demand of the same will be increased. 6. New buyers - if the prices will be low more number of people will be able to a for the product. In turn the demand will rise with the decline in prices. Regards
