When a warehouse opened, it had an inventory of 6,000 items. every month, the inventory increases by 3,000 items.
which graph has the most appropriate scales and units for this situation?

The first two graphs are the exact same but it is the first two.

Step-by-step explanation:

In the beginning ,number of inventory in the warehouse =6,000

 Increment in each month in inventory in the warehouse=3000

So, writing the above situation in terms of linear equation

 if,y is the number of inventory after x months

 y=6000 +3000x

Correct graph is attached below

⇒Items in Inventory(Thousands) ----X axis

⇒Number of Months since Opening----Y axis

if x = 1, then the answer is 3.5
