You are creating a line graph with data from an experiment tracking the growth of a tree over the last year. it is most important that you label the independent variable on the

a.) x-axis.
b.) y-axis.
c.) title of the graph.
d.) line you are graphing.

A)The independent variable should be labeled on the X-axis.

Explanation:

•Dependent variables: properties that the researcher or observer can not directly control. These properties usually change as an effect of the change in other property.

•Independent variables: properties whose value can be picked or determined by the researcher to see if they are the cause of a change in the dependent variable.

If you are tracking the growth of a tree over the last year, you would like to know the influence of time on the growth of the tree. You probably have selected some values of time to measure the growth of the tree, it could be every fifteen days, every month or every quarter. As you can influence or pick the value of the time, it is your independent variable, and you can analyze the influence of the chance of time on the tree growth, which is your dependent variable.

Finally, we can say that the time should be labeled on the x-axis, since it is the independent variable.
