Define and describe the Coordinate Plane: A two-dimensional flat surface formed by the intersection of a horizontal x-axis and vertical y-axis (perpendicular to each other at the origin (0,0)), used to uniquely locate points using ordered pairs of numbers.
Which directions are considered to positive movements on a coordinate plane? Right and Up
Which directions are considered to be negative movements on a coordinate plane? Left and Down
Describe the format of a coordinate or ordered pair and give 3 examples: An ordered pair follows the format $(x, y)$, where $x$ is the horizontal (x-axis) value and $y$ is the vertical (y-axis) value, corresponding to a point's position relative to the origin.
Example 1: $(2, 5)$
Example 2: $(-3, 1)$
Example 3: $(0, -4)$
