Graph b value of sarah’s car 4. what is the loss in value between 2005 and 2006 5. what is the dependent variable in this graph 6. explain how to interpret the data for this graph. (what is happening to the value of sarah‘s car overtime)

4) The lost value is $4500.

5) The values in a $ are Dependent variable in the graph.

6) Time(year) is inversely proportional to the values in $.

Explanation:

4) To calculate a loss between 2005 and 2006 we will find the value on the y-axis for 2005(which is on the x-axis)  from the graph and subtract it by the value  on the y-axis for 2006(which is on the x-axis)  from the graph.  

 loss between 2005 and 2006 = $14500-$10000

                                                            = $4500

Percentage of loss is 31.03%

5) A dependent variable is a variable being tried and estimated in a logical test.  The dependent variable in the graph is the value of the car that is given in the Dollar($). We can see that by the increase of the time there is an effect on the value of the car and the dependent variables are taken on the y-axis.

6) From the graph, It is shown that with an increase in time(year) the value of Sarah's car decreases and with the decrease in time its value increases. So it is clear that time is inversely proportional to the value of the car. By every passing year, the value of the car decreases.
