Question

Which of the following images represents an integer number line perfectly?

• A.
• B.
• C.

Answer 1

The correct option is C

Natural numbers and their negatives including zero belong to integers, but fractions and decimals do not. As a result, this picture does not depict an integer number line perfectly.
Positive numbers are always on the right side of zero on an integer number line, while negative numbers are always on the left side of zero. Arrowheads on both ends of the line indicate that the line continues forever in both positive and negative directions. As a result, this picture does not perfectly depict an integer number line with no arrowheads on both ends.
