Question

Eduardo used a number line model shown to model an equation. Which of the following could be Eduardo's equation? (1 point) Responses −5−3=−8 negative 5 minus 3 is equal to negative 8 −5+8=3 negative 5 plus 8 is equal to 3 5+(−8)=−3 5 plus negative 8 is equal to negative 3 5+(−3)=2

Answer 1

To determine which equation Eduardo modeled using the number line, we can evaluate each option:

1. **−5 − 3 = −8**:
If we start at -5 and move 3 units to the left, we'll end up at -8.
This equation is correct.

2. **−5 + 8 = 3**:
If we start at -5 and move 8 units to the right, we'll end up at 3.
This equation is correct as well.

3. **5 + (−8) = −3**:
If we start at 5 and move 8 units to the left, we'll indeed reach -3.
This equation is also correct.

4. **5 + (−3) = 2**:
If we start at 5 and move 3 units to the left, we will arrive at 2.
This equation is also correct.

Since multiple equations could potentially be modeled using a number line, we can pick any one of them. However, if you are looking for the most straightforward equation in this context, **−5 − 3 = −8** is often the type of operation that corresponds directly with a leftward movement on a number line.

Thus, a possible choice for Eduardo's equation could be:
**−5 − 3 = −8**.
