Answer: b. Lin buys a pack of 87 pencils. She gives 39 to her teacher and shared the remaining pencils between herself and 3 friends.
Step-by-step explanation:
Lin buys 87 pencils which is why the entire number line adds up to 87.
She gave 39 of these pencils to her teacher which s why there is a section of the number line that is unlike the rest and is 39 in number.
The rest of the number line is a set of 4 spaces which are equal.
Lin shared the remaining pencils between herself and 3 friends which means she shared the pencils with 4 people. These four equal quantities of pencils are the 4 spaces.

We can see that
both lines intersects at origin
so, the solution is x=0 and y=0
now, we will check each options
option-A:


now, we can set them equal
and then we can solve for x



now, we can find y


so, solution is x=0 and y=0
so, this correct...........Answer
