Answer:
I agree with Claire's representation. Sea level is considered as zero, going up in the number line is positive and going down in the number line is negative.
The location 10 feet above sea level is correct. We have to count 10 spaces going upwards from zero. This location is represented by the integer 10.
The location 10 feet below sea level is correct. We have to count 10 spaces going downwards from zero. This location is represented by the integer -10.
Step-by-step explanation:
The attached picture shows two points:
The red point represents 10 feet above sea level. (Integer: 10)
The blue point represents 10 feet below sea level. (Integer: -10)
Sea level is zero.
