It is very common to use, but it is not the only variable you can use.

Is a variable minus a variable a monomial?
Not always. It could be a constant. For example x is one variable, and y = x-2 is another variable. Then x - y = x - (x-2) = 2.
Is a variable a variable expression?
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).
Previous Next Help Exit On a graph where is the independent variable placed?
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.
In the ordered pair x y the independent variable corresponds to?
By convention, 'x' is almost always the independent variable, but it doesn't have to be.
What is the slope of the graph of the equation x equals 3?
x=3 means that the x variable always stays constant, so the y variable can change as much as it wants, but x will always be 3. on a graph, this would like a vertical line. (It should be perpendicular to the x variable's line...if that helps a visual:P)
What kind of variable is always changing?
the y variable always changes and x is constant

What variable is always graphed as the independent variable?
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.

Is the factor that may change in response to the independent variable?
Since y depends on x and x is the independent variable, y has to be the dependent variable. That means that y always changes because of x.

What is the factor that may change in response to the independent variable?
The dependent variable may change in response to the manipulated variable.
Which axis holds the independent variable?
The independent variable is typically placed on the x-axis in a graph or chart.
Which type of variable is plotted on the x-axis the y-axis?
Always when using a line graph use the x-axis for independent variable and the y-axis for dependent variable.
Can a variable be divided by a non variable?
This X2/X = X ==========yes X/3 = ?????? ==============No Yes it can. However, dividing by a variable doesn't always work since the variable could evaluate to zero, and you cannot divide by zero. Similar is true if the non-variable is zero.
