Explanation:

Step1: Identify positions of K and L

K is at -1, L is at 9 on the number line.

Step2: Calculate distance

Distance between two integers \( a \) and \( b \) is \( |a - b| \). So, \( | -1 - 9 | = | -10 | = 10 \), or count units between -1 and 9: from -1 to 0 is 1, 0 to 9 is 9, total \( 1 + 9 = 10 \).

Answer:

10
