It enables you to show a relationship where an increase in one variable results in a decrease in the other.
When one variable is said to be dependent on another, it means that the value of the dependent variable is influenced or determined by changes in the other variable, known as the independent variable. For example, in a relationship where an increase in temperature (independent variable) leads to an increase in ice cream sales (dependent variable), ice cream sales vary based on the temperature. This relationship highlights causation or correlation between the two variables.
dependent variable
A direct relationship in which two factors increase or decrease together is called a positive correlation. In this scenario, as one variable rises, the other variable also rises, and similarly, if one falls, the other falls as well. This relationship is often represented graphically with an upward-sloping line.
A positive correlation between two variables is shown by a scatter plot where the points trend upward from left to right. This indicates that as one variable increases, the other variable also tends to increase. The relationship can be represented by a line of best fit with a positive slope.
decreases
A dependent variable increases when an independent variable increases in a direct relationship. This means that as one variable increases, the other variable also increases.
The other can increase, decrease or stay the same. It depends on the relationship between the two variables.

A negative correlation is a measure of the linear component of a relationship where one variable increase as the other decrease.
One variable can affect another through a causal relationship, meaning changes in one variable directly cause changes in the other. This relationship can be positive (both variables increase or decrease together) or negative (one variable increases while the other decreases). The strength and direction of this effect can be quantified through statistical analysis.
An inversely proportional relationship shows that as one variable of an equation increases, the other will decrease. A directly proportional relationship shows that as one variable increases, the other increases as well.
Correlation

The volume of gas
A positive correlation between two variables means that there is a direct correlation between the variables. As one variable increases, the other variable will also increase.
