Always isolate the varible
the y variable always changes and x is constant
The variable in the experiment that is always the same
1
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).
x is used a lot to represent an independent variable. When time is the independent variable t is often used as well.
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
