Concept:A supply curve shows the relationship between price and quantity supplied.Explanation:As price increases, quantity supplied also increases.Therefore, the supply curve slopes upwards from left to right.This direction indicates that price and quantity supplied move in the same direction.The slope is calculated as ΔQΔP.Since both price and quantity supplied increase together, the slope value is greater than zero.This is called a positive slope.A negative slope would show the curve falling from left to right, which is not the case for supply.Thus, the correct option is the one that states a positive slope.
