Always isolate the varible
the y variable always changes and x is constant
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).
The independent variable is always graphed on the x-axis. This variable is manipulated or controlled by the experimenter and is used to examine its effect on the dependent variable.
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
