How do you expect us to answer your question if we dont know if it is an equation but 7.0
Given that Sara put 7 boxes in her closet.
So number of boxes = 7
Then it says that each box is for holding a different type of seashell. So far, there are 0 shells in each box.
So the number of seashell in 1 box = 0
We need to find about how many shells does Sara have.
To find that we will just multiply (number of boxes) by (number of seashell in 1 box). Which is given by 7 times 0.
we know that product of a number and 0 is always 0.
Hence final answer is 0 seashell.
Assuming if you are looking for an equation
I can say that the X-intercept= 16/9
but with an equation it would be 9x/4(-4)
