the graph shows how the value of two used cars changed during a 10 year period.

after _ years, the cars both have a value of $_

8,10,4,6,000,15,000,18,000,9,000

To determine the missing information, we need to understand the given data accurately. However, the provided data seems to be disorganized and incomplete. It is not clear how the values are distributed over the 10-year period, as no specific information or pattern can be deciphered from the given numbers.

To properly construct a graph showing the value changes of two used cars, we would need the value data for each year across the 10-year period for both cars. Additionally, the missing values for the specific year and final value should be provided.

Please provide complete and accurate data to create an informed graph and answer your question accurately.
