Always isolate the varible
the y variable always changes and x is constant
1
The variable in the experiment that is always the same
dependent variable always go on y.axis on the graph.
no
constant variable
Yes. A variable by itself, or anything that contains a variable, would be a variable expression (unless the variable cancels out, as in "x - x", which always has the same value).
It is very common to use, but it is not the only variable you can use.
Always changing
The independent variable is always on the x-axis of a coordinate plane. The dependent variable is always on the y-axis. This is true because y always depends on x.
no. a variable is usally noted by an alphabetical number or greek symbol
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.
