Answer: 10
====================================================
Step-by-step explanation:
Let point M be at zero on the number line.
- From K to M is 7 spaces
- From M to L is 3 spaces
Overall, the total distance is 7+3 = 10 units.

Another route:
You can subtract and apply absolute value.
| K - L | = | -7 - 3| = | -10 | = 10
Or,
| L - K | = |3 - (-7)| = |3 + 7| = |10| = 10
