Question

For the equation given below, find the dependent and independent variables are

$y=\frac{1}{7}(6x+5)$.

• A. $y$ is independent variable and $x$ is dependent variable.
• B. $x$ is independent variable and $y$ is dependent variable.
• C. $x$ is dependent variable and $y$ is also dependent variable.
• D. $y$ is independent variable and $x$ is also independent variable.

Answer 1

The correct option is B $x$ is independent variable and $y$ is dependent variable.

The given equation is $y=\frac{1}{7}(6x+5)$

Here, $x$ is free to take any value. So, $x$ is independent.

But any change in the value of $x$(input) will influence the change in value of $y$(output).

$⟹y$ changes as $x$ varies

So, $y$ depends on the value of $x$

Thus, $y$ is dependent variable.

Hence, option B is correct.
