$y = 2 x$ $y=2x$

Explanation:

The word product refers to the answer you get from a multiplication.

The word variable within the context of Algebra refers to a value that is allowed to change. This is represented by some single letter
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$Putting this into the context of your question.$ $color(blue)("Putting this into the context of your question.")$

$Answer = 2 \times a unknown number \to y = 2 x$ $color(brown)("Answer = "2xx" a unknown number"color(blue)(-> y=2x))$

Where $x$ $x$ can take on any value. So it is the independent variable.

Where $y$ $y$ is totally dependant on the value of $x$ $x$ so it is the dependant variable.
