Option D is right

Step-by-step explanation:

Given that the owner of an office supply store initially spends $400 to bring in a new line of pens that he wants to sell. He buys a pack of 10 pens for $3 and sells each pack for $5.

3 dollars fetch 10 pens

400 dollars fetch 4000/3 =1333.33 pens

10 pens sold for 5 dollars

Hence a pack of 10 pens fetch 5-3 = 2 dollars as profit.

The store owner has chances for break even as he has positive contribution.

Fixed costs = 400

This will be nullified when 2x100 dollas are earned extra

i.e. 100x10=1000 pens are sold

So option D is right

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
