Answer 1

To compute \(-2 + (-5)\) using a number line, we can follow these steps:

1. Start at -2: Locate -2 on the number line.
2. Move left: Since we are adding a negative number (-5), we need to move left on the number line. Move left 5 units from -2.

Here’s the movement:

• From -2, moving left 1 unit you get to -3.
• Moving left 2 units you get to -4.
• Moving left 3 units you get to -5.
• Moving left 4 units you get to -6.
• Moving left 5 units you get to -7.

So, \(-2 + (-5) = -7\).

Thus, the final answer is:

\[ -2 + (-5) = -7 \]
