? New Vocabulary

? Write each term on a sticky note using the Frayer Model

? Ordered Pair ? a set of numbers used to identify points EX: (2,3) ? First Coordinate ? the first number in an ordered pair ? Second Coordinate ? the second number in an ordered pair ? Coordinate Plane ? a plane formed when a horizontal number line intersects

with a vertical number line.

Lesson 14 ? Ordered Pair

? How to write an ordered pair:

? An ordered pair is written as (x, y) ? X represents the first number in the ordered pair ? it is called the x ? coordinate ? Y represents the second number in the ordered pair ? it is called the y ? coordinate

? How to use an ordered pair to find a point on a plane:

? Ordered pairs are like a set of directions; ? The first coordinate (x ? coordinate) tells you where to go in one direction ? The second coordinate (y ? coordinate) tells you where to go in the second direction.

? EX: To find point A (3,4):

? First move 3 units to the right on the x ? axis (or horizontal number line) ? Then move 4 units up on the y ? axis (or vertical number line)
