A line graph can tell you how changes in one variable are related to changes in the other. A line graph cannot show causality. A line graph can show non-linear relationships which some other analytical techniques may not identify. In particular, they are good for identifying relationships between the variables that change over the domain. A line graph can also help identify points where the nature of the relationship changes - eg tension and breaking point, or temperature and phase.
The spread of observations about the "line of best fit" gives a measure of how closely the variables are related and how much of the measurement is systemic or random error.
Line graph is used to show relationship between two variables.
linear graph between an independent and independent variable
A scatter plot.
Line
there is a strong relationship between the variables
What dose a line graph tell you about the relationship between the variables in an experiment
a bar grapg can be used
The extent of changes between the variables throughout different conditions or circumstances.

Line Graph
A line graph is often useful in visualizing the relationship between two variables. But bear in mind that such relationships are sometimes so complicated that they are difficult to graph.
A scatter plot.
Line
there is a strong relationship between the variables
The relationship is a function if a vertical line intersects the graph at most once.
