Question

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

$y=\frac{4}{3}x-7$.

• 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 $y=\frac{4}{3}x-7$

In this equation, $x$ is free to take any value. So, $x$ is independent variable.

But, any change in the value of $x$ will influence the value of $y$.

So, $y$ depends on $x$ and thus, it is dependent variable.

Hence, option B is correct.
