This week I learned how to illustrate relations between two variables and represent this relation in some form. I learned to illustrate the relationship between these two variables doing the following steps.

Ex Relation.

The grade you make on a test depends on the number of questions you answer correctly.

In this example the independent variable is the number of questions you answered correctly. The independent variable is also known as the input. This variable is known as the independent variable because the number of the independent variable is not depending on anything. The dependant variable in this example is the grade. The dependant variable (also known as the output) is called the dependant variable because its number depends on what number independent variables is.
