Question

How do you translate the word phrase into a variable expression: product of 2 and a number?

Answer 1

`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
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
`color(blue)("Putting this into the context of your question.")`

`color(brown)("Answer = "2xx" a unknown number"color(blue)(-> y=2x))`

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

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