Answer 1

To solve the expression \(-4 + 7\) using a number line:

1. Start at \(-4\).
2. Move to the right because you are adding a positive number (7).
3. Count 7 units to the right from \(-4\):

- From \(-4\) to \(-3\) is 1 unit.
- From \(-3\) to \(-2\) is 2 units.
- From \(-2\) to \(-1\) is 3 units.
- From \(-1\) to \(0\) is 4 units.
- From \(0\) to \(1\) is 5 units.
- From \(1\) to \(2\) is 6 units.
- From \(2\) to \(3\) is 7 units.

After moving 7 units to the right from \(-4\), you land on \(3\).

Therefore, the solution to \(-4 + 7\) is \(3\).

The correct answer is **3**.
