The horizontal number line is called the x -axis, and the vertical number line is called the y-axis. These two number lines define a flat surface called a plane, and each point on this plane is associated with an ordered pair of real numbers (x,y). The first number is called the x-coordinate, and the second number is called the y-coordinate. The intersection is the origin: (0,0).

It also explores angles in the Cartesian coordinate system, covering quadrants, angles in standard position, and coterminal angles. This foundation is critical for understanding Trigonometry's broader concepts, with practical examples and checkpoints to ensure comprehension.

It covers the classification of numbers (natural, whole, integers, rational, and irrational) and explains how to plot points and graph equations on the Cartesian plane. The section also discusses intervals and the distance formula, providing foundational knowledge for working with functions and graphs in Algebra.
