What dose a line graph tell you about the relationship between the variables in an experiment
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
The slope of a line is the same thing as the rate of change between two variables in a linear relationship.
This is called an "inverse" relationship.
