Answer:
A dependent variable is a variable whose value depends upon some other variable where as, an independent variable is a variable whose value doesn't depend upon any other variable.
Explanation:
For example:
Let us take an expression y=3x+1, where x has some given values { let's assume x lies between 0 to 100}
so we can see that the value of y is depending upon the value of x ,as for every different value of x we will get a different value of y. So we can say that y is a dependent variable.
On the other hand, x doesn't depend on y as its values are already mentioned or specified so it's an independent variable.
