Density & Graphing

Density
- The density of an object is its mass divided by its volume
  - d=m/v
     - Usually expressed in : kg/L, kg/m^3, kg/m^2
     - Examples : d= 135kg / 65L = 2.1kg/L
                            d= 54kg / 27m^3 = 2kg/m^3
                            d= 1200kg / 51m^2 =24kg/m^2

Graphing
*All graphs must contain 5 important things*
1) Labelled Axis
2) Appropriate Scale
3) Title
4) Data Points
5) Line of Best Fit
Example of proper graph :

- Three things can be done when working with graphs
1) Reading the graphs
2) Find the slope (rise/run)
3) Find the area under the graph

- Linear Graph :

- Inverse Graph :
