Lesson 3-3 Pages 112-115 The Coordinate Plane Lesson Check 3-2

2
What you will learn! How to graph points on a coordinate plane.

3
Coordinate plane Ordered pair Coordinate grid x-coordinate x-axisy-coordinate y-axisquadrant Origin

4
What you really need to know! The coordinate plane is used to locate points. The horizontal number line is the x-axis. The vertical number line is the y-axis. Their intersection is the origin.

5
What you really need to know! Points are located using ordered pairs. The first number in an ordered pair is the x-coordinate; the second number is the y-coordinate.

6
What you really need to know! The coordinate plane is separated into four parts called quadrants.

7
Quadrant IQuadrant II Quadrant IIIQuadrant IV

9
Example 1: Name the ordered pair for point R y x (-2, 4) R

10
Example 2: Graph and label the point M(3, 5). M y x

11
Use the map of Utah shown below. In which quadrant is Vernal located? Example 3: Quadrant I

12
Name a city from the map that is located in quadrant IV. Example 4: Bluff
