Identify the integers represented by letters on the number line and write the mathematical statement for the indicated segments.

Here are the solutions to the questions.

Question 11:

a) Write the integers represented by the letters.
From the number line:
A = -4
B = -1
C = 0
D = 2
E = 4
F = 6
The integers represented by the letters are: A = -4, B = -1, C = 0, D = 2, E = 4, F = 6.

b) Write the mathematical statement for the above number line.
The number line shows two segments indicated by brackets:

• The segment from C (0) to E (4) can be represented as $0 \le x \le 4$.
• The segment from A (-4
