1. THE COORDINATE PLANE

2. Coordinate Plane
Formed by the intersection of two number lines

3. Parts of the Coordinate Plane
x-axis: the horizontal number line
y-axis: the vertical number line
Quadrants: the 4 areas the coordinate plane is divided into
Written as Roman numerals
Origin: the intersection point of the number lines; (0, 0)
