Determine the answer to (-3) + (-5) and explain the steps using a number line

Imagine negatives as a form of debt, you start out owing someone 3 dollars, (-3); and then you borrow 5 more from them, (-5), add up the total amount of money you owe, which equals (-8). Using a number line, place a dot over where negative 5 is located, before moving back 3 steps to where negative 8 is located. This will give you your problem and answer, (-5)+(-3)=(-8)

The answer is option c.
