Using Number Lines to Represent Integers
An integer is a whole number that comes in three types: positive, negative, or 0. It is not a fraction or decimal.
Integers can be on the left-hand side or right-hand side of zero on the number line.
Zero is in the middle of the number line. Positive integers are on the right side of 0. Negative integers are on the left-hand side of 0.
A step-by-step guide to present integers on the number lines
Step 1: First identify whether the number is a negative or positive integer.
Step 2: If it is a negative integer, it is on the left side of the zero on the number line.
Step 3: If it is a positive integer, it is on the right side of the zero on the number line.
Using Number Lines to Present Integers – Examples 1:
Graph 9 on the number line.
Solutions:
Since 9 is positive, it is on the right side of 0 on the number line.
Using Number Lines to Present Integers – Examples 2:
Graph \(-3\) on the number line.
Solutions:
Since \(-3\) is negative, it is on the left side of 0 on the number line.
