Answer:
along a track in opposite directions.
Explanation:
In Economics, there are primarily two (2) factors which affect the availability and the price at which goods and services are sold or provided, these are demand and supply.
The law of demand states that, the higher the demand for goods and services, the higher the price it would be sold all things being equal.
On the other hand, law of supply states that the higher the price of goods and services, the lower the supply.
This ultimately implies that, there exist a negative relationship between the quantity of goods demanded and the price of a good. Thus, when the prices of goods and services in the market increases or rises: there would be a significant decline or fall in the demand for this goods and services.
According to the law of demand, price and quantity move along a track in opposite directions i.e the quantity of goods or services demanded is inversely proportional to the price of the goods or services at a specific period of time.
