Understanding Relative Numbers and Number Lines

This page introduces fundamental concepts of relative numbers and their representation on a number line. The content focuses on positive and negative numbers and their relationships.

Definition: Relative numbers include both positive and negative numbers, with zero as the reference point.

Example: Numbers like +16, +11 (positive) and -7, -11 (negative) are shown on the number line.

Highlight: Negative numbers are always less than zero, while positive numbers are greater than zero.

Vocabulary:

• Abscissa: The horizontal coordinate in a coordinate system
• Opposite numbers: Numbers with the same distance from zero but opposite signs

Example: Point E(-2,75) demonstrates how coordinates are plotted on a number line.
