What is a number line
A number line is a visual representation of numbers arranged in a linear or sequential order.
It provides a way to illustrate the relative magnitudes and relationships between different numbers.
The number line is typically a straight line that extends infinitely in both directions. The midpoint of the line is often labeled as zero, and positive numbers extend to the right, while negative numbers extend to the left.
The mark is on the negative section since it is on the left of zero. After zero, we can count 2 points but not up to 3. hence the number should be -2.1/4
