Part 1
1. What is the total height of the climbing wall? Represent the situation with a number line. Then, explain how you found your answer.
The climbing wall is

(Type an integer or a decimal.)
Part 2
Which number line represents the situation?
The total height of the climbing wall is 21 feet - (-9 feet) = 30 feet tall.
The number line that represents the situation is:
-9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21.
Part 1:
The total height of the climbing wall can be found by adding the height above the ground level (21 feet) to the depth underground (9 feet). So, the total height of the climbing wall is 21 + 9 = 30 feet.
Part 2:
As an AI text-based bot, I am unable to display or provide visual images. However, a number line representation of the situation can be drawn with 0 representing ground level, and then marking the climbing wall starting 9 feet below ground level and extending 21 feet above ground level.
Part 1:
To find the total height of the climbing wall, we need to calculate the difference between its highest point and its lowest point.
The climbing wall starts at 9 feet below the ground level, so the lowest point is -9 feet. It extends to 21 feet above the ground level, so the highest point is +21 feet.
To find the total height, we subtract the lowest point from the highest point:
Total height = highest point - lowest point
= 21 feet - (-9 feet)
= 21 feet + 9 feet
= 30 feet
Therefore, the total height of the climbing wall is 30 feet.
Part 2:
Unfortunately, without any options or descriptions of number lines, I am unable to determine which number line represents the situation. Please provide more information or options for me to assist you further.
