In the equation \(y = 3x\), the variable descriptions are as follows:
- \(y\) is the dependent variable, often representing the output or outcome of a function.
- \(x\) is the independent variable, usually representing the input or variable that can be manipulated.
In this specific equation, it indicates that \(y\) is three times the value of \(x\), reflecting a linear relationship between the two variables with a constant slope of 3.
