Here are the essential concepts you must grasp in order to answer the question correctly.
Inequalities
Inequalities are mathematical expressions that compare two values or expressions, indicating whether one is greater than, less than, or equal to the other. In this context, the symbol '≥' means 'greater than or equal to,' which is essential for understanding the relationship between the numbers involved.

Number Line
A number line is a visual representation of numbers in a straight line, where each point corresponds to a number. It helps in understanding the relative positions of numbers, such as positive and negative values, which is crucial for evaluating statements involving inequalities.

Negative and Positive Numbers
Negative numbers are values less than zero, while positive numbers are greater than zero. Understanding the properties of these numbers is vital for evaluating inequalities, as it allows one to determine the truth of statements like '0 ≥ -6' by recognizing that zero is indeed greater than negative six.
