# Coordinate Plane

Coordinate Plane.  It is made up the X-axis (a horizontal number line) and Y-axis (a vertical number line). The X and Y axes intersect at the origin (0,0) and are perpendicular to each other.

We use ordered pairs of numbers (X, Y) to locate points in the plane. To find a point on the plane, first move horizontally along the x-axis and locate the X value;  then move vertically to locate the Y value; draw a point where they meed, as shown.

Coordinates of a point  (X, Y)
Coordinates give the position of a point on each axis of the Coordinate Plane.
Each coordinate gives the X-value first, followed by the Y-value.
Coordinates are written in parentheses separated by a comma.
The  coordinate plane has four quadrants which are labeled counter-clockwise (using Roman Numerals)

LINEAR RELATIONSHIPS
A function represents a dependence of one quantity on another and can be described in a variety of ways. In this unit, in addition to deriving and interpreting y=mx and y=mx + b, students will represent directly proportional and linear relationships using verbal descriptions, tables, graphs, and formulas, and translate among these representations.

Roman Numerals

Roman numerals were used by the Romans as their numbering system. They are expressed by letters of the alphabet:

 I = 1 V = 5 X = 10 L = 50 C = 100 D = 500 M = 1000
