Supply curve is a curve showing positive relationship between the price and the quantity supplied.
Explanation:
The supply curve is an upward sloping curve which tells a relationship between the price of a commodity and the quantity of the commodity supplied in the market. Since there is a direct relationship between that price and the quantity, therefore the curve is upward sloping.
For example, when the price of coffee increases in the market, the quantity of the pens supplied in the market will be increased by the producers of the pen in the market.
