Yes normally it can
The graph must be a straight line, and it must pass through the origin.
Because the temperature varies presumably.
up down side to side all that stuff :]
Analysis.
Yes, properties vary systematically. So there is a repeating pattern in graph.
When a graph shows a trend that is noticeable. Such as a line or a curve in a certain shape.
yes
a line graph will join all of the points yet a best fit graph will only join the dots which follow the pattern.
Yes normally it can
The line that reflects the general pattern of a graph is called a trend line.
A general pattern found on a graph of radioactive decay is that the number of radioactive atoms decreases exponentially over time. The graph typically shows a steep initial drop followed by a gradual decrease as the radioactive material decays.
The graph must be a straight line, and it must pass through the origin.
does not form a staight line on a graph
Because the temperature varies presumably.
