To determine which points on the number line show how your amount of money changed, let's establish what each point represents:

  • Let B represent the amount of money you had before paying your friend, which is $10 less (so if you had $0, B would be -$10).
  • Let C represent the amount of money you have after paying back your friend.

When you pay back your friend $10, your amount of money decreases, so you would be moving from B (before payment) to C (after payment).

Thus, the correct response is:

from B to C
