It represents, approximately, a linear relationship with a negative gradient.
an exponential function flipped over the line y=x
The best fit line is basically the average of a graph; it represents where, when, etc. the majority of the event occurred.
Bar graph
Distance and time
A graph going down from GAS to SOLID best represents a change in phase from a gas to a solid.
Line Graph
a bar graph is best used for comparing amounts, a line graph best represents a steadily increasing value. For example prices of a shirt (line graph), or viscosity of liquids (bar graph).
The area that best represents it

Velocity change vs Time
In which of the following situations would a line graph be best?
While a line graph can help with interpretation by showing the changes in values as a line, there are times when it is not the best king of graph for a particular situation. That is why other kinds of graphs have been developed.
It would help to have the graphs to choose from!
It represents, approximately, a linear relationship with a negative gradient.
