Identify, represent, and analyze two quantities that change in relationship to one another in real-world or
mathematical situations.

Use tables, graphs, and equations to represent the relationship between independent and dependent variables.

Arkansas Academic Standards:
6.EE.C.9

Use variables to represent two quantities in a real-world problem that change in relationship to one another:

Write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable

Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation

For example: In a problem involving motion at constant speed, list and graph ordered pairs of distances and times, and write the equation d = 65t to represent the relationship between distance and time.

Note: The independent variable is the variable that can be changed; the dependent variable is the variable that is affected by the change in the independent variable.

Use variables to represent two quantities in a real-world problem that change in relationship to one another. e.g., In a problem involving motion at constant speed, list and graph ordered pairs of distances and times. Given a verbal context and an equation, identify the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation. e.g., Given the equation d = 65t to represent the relationship between distance and time, identify t as the independent
variable and d as the dependent variable.

6th Grade Math - Represent Relationships [2 variables] Lesson

If a relationship exists between two values, say x and y, such that one value, say y, is dependent on the other value, x, then x is referred to as the independent variable, and y is referred to as the dependent variable.

Consider a known relationship, such as the relationship between inches and feet. There are 12 inches in 1 foot. What if we want to know the number of inches in a given number of feet? Then, the number of inches is dependent on the number of feet. This relationship could be represented by the equation 12x = y, where x is the number of feet, and y is the number of inches. In this situation, x is the independent variable and y is the dependent variable.

What if we want to know the number of feet in a given number of inches? Then, the number of feet is dependent on the number of inches. This relationship could be represented by the equation $\frac{1}{12}$x = y, where x is the number of inches and y is the number of feet. In this situation, x is the independent variable and y is the dependent variable.

Note that while you will often see the letters x and y used for the independent and dependent variables, respectively, it is the mathematical language and/or situation which dictates independent and dependent - not the letter used for the variable.

Mathematical relationships are often represented by equations, tables, and/or graphs.

Example:

The number of yards times 3 equals the number of feet. So, an equation which could be used to find the number of feet based on the number of yards is 3y = f.
