1. 5-1 The Coordinate Plane Introduction

2. Coordinate Graph

3. Y-axis X-axis The four quadrants of the coordinate plane. Quadrant I Quadrant II Quadrant IV Quadrant III

4. Y-axis X-axis Signs of the quadrants. (+,+ ) (+,- ) (-,- ) (-,+ )

5. Vocabulary Words Axes - two perpendicular number lines used for locating points Origin – the intersection of the two axes Y-axis – the vertical number line X-axis – the horizontal number line

6. The Ordered Pair (5,10) X- coordinate Y- coordinate

7. Y-axis X-axis The Origin Point Origin Point (0,0)

8. Always start at the origin to plot a point.

9. Y-axis X-axis Direction of Movement for the X-Coordinate If the x- coordinate is positive move this way If the x- coordinate is negative move this way

10. Y-axis X-axis Direction of movement for the Y-coordinate If the y - coordinate is positive move this way If the y - coordinate is negative move this way

11. Y-axis X-axis Name the given point. (1,3) (-5,-1) (-2,1) (4,0)

12. Y-axis X-axis (4,4) (-3,-1) First move out on the X-axis Next move on the Y- axis How To Plot a Point on the Coordinate Plane
