When an increase in the value of one variable quantity results in a decrease in the value of another, the two quantities are considered to be inversely related or negatively correlated. This means that as one quantity rises, the other falls, illustrating a reciprocal relationship between them. Examples include supply and demand, where an increase in supply typically leads to a decrease in price.
