The density of an object is it's mass divided by it's volume
and is usually expressed in
More on Density
All graphs must contain 5 important things:
1. Labelled axis
2. Appropriate scale (the data should take up at least 2/3 of the graph)
3. Title
4. Data points
5. Line of best fit
1. Read the graph (before you start taking information from it, read the whole thing!)
2. Find the slope (rise over run)
rise
run
3. Find the area under the graph (you will, in some cases, need to split the space under the graph into manageable sections so you can get the area of each and add it together)
How to Find Slope
The slope of a line is rise over run.
The rise on the graph would be the Y axis, while the run would be the X axis.
To find the slope, plot the data points and find the line of best fit. (You can try placing your data points in such a way that it corrisponds to the scale so that the line of best fit starts from the bottom corner.)
Once you have your line of best fit, choose a point on the line and find out the rise # and the run #.
Divide the rise by the run, and you have your slope!
