# 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.
