Objective The student will be able to: graph ordered pairs on a coordinate plane. • Coordinate plane - a coordinate system formed by the intersection a horizontal number line, called the x – axis, and a vertical number line called the y-axis. • of Points are labeled with capital letters. • Ordered Pair – a pair of numbers that can be used to represent a point in the coordinate plane, often expressed as ( x , y ). • The first coordinate, x, of an ordered pair is the x - coordinate . It tells how far left or right to move from the origin. • The second coordinate, y, of an ordered pair is the y - coordinate. It tells how far up or down to move from the origin. • Quadrants - the four regions that the coordinate plane is divided into. y-axis x is positive x is negative y is positive II x-axis III I origin IV y is negative The graph of (x,y) is the point in the plane that corresponds to the ordered pair (x , y ). The Origin is always point ( 0 , 0 ). Ordered pairs are used to locate points in a coordinate plane. y-axis (vertical axis) 5 5 -5 x-axis (horizontal axis) -5 origin (0,0) In an ordered pair, the first number is the x-coordinate. The second number is the y-coordinate. Graph. (-3, 2) 5 • 5 -5 -5 What is the ordered pair for A? 1. 2. 3. 4. (3, 1) (1, 3) (-3, 1) (3, -1) 5 •A 5 -5 -5 What is the ordered pair for B? 1. 2. 3. 4.
