model the expression on the number line.

Explanation:

Step1: Identify the expression (assuming a common example like starting at 0 and moving left, or a given expression). Since the number line is from -6 to 0, let's assume we need to model an expression like starting at 0 and moving left (negative direction) or combining movements. Wait, the problem says "Model the expression on the number line" but the expression isn't given. Wait, maybe a common problem is like -3 + (-2) or similar. Let's assume a typical problem: say we have to model -4 - 2 (which is -6).

Step2: Start at -4 (or 0, depending on the expression). Wait, the number line has marks at -6, -5, -4, -3, -2, -1, 0. Let's suppose the expression is, for example, starting at 0 and moving 6 units left (to -6). Or starting at -2 and moving 4 units left (to -6).

But since the problem is incomplete (no expression given), but assuming a standard problem: let's say the expression is -3 + (-3) = -6.

Step3: Locate the starting point. If starting at 0, move 3 units left to -3, then another 3 units left to -6. Mark the movements on the number line.

Wait, the original problem might have an expression missing. But since the number line is given with -6 to 0, let's assume the expression is, for example, representing -6. So we mark -6 on the number line.

Answer:

(Assuming the expression is to represent -6, the point at -6 on the number line is the model. If the expression was, say, -3 + (-3), we move from 0 left 3 to -3, then left 3 more to -6. But without the expression, but based on the number line, the key is to model the expression's result. Since the number line has -6, -5, etc., the answer would be marking the correct point. If the expression is, e.g., -4 - 2, the result is -6, so the point at -6.)
