A study showed that the ratio of the number of people who use social media to the number of people who
don't use social media is 2:3. Based on the ratio, how
many people in a town of 500 people don't use social
media.
Two classmates solved this problem and their work is
shown below. Which classmate solved the problem
correctly? Explain the error in the classmate who
solved it incorrectly.

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
