EXAMPLE #1

Teaching Your Class ______Graphing Points  The rectangular coordinate system is formed by y-axis taking two number lines, and placing them 6 perpendicular to each other, crossing at 0 on both 4 lines (this crossing point is the origin). Quadrant II Quadrant I 2  A point is given by the ordered pair . The x- coordinate tells us how to move horizontally, and the y-coordinate tells us how to move vertically in 6 4 2 2 4 6 x-axis 2 the coordinate system. Quadrant III Quadrant IV  Every point will either fall into one of the four 4 Quadrants (I, II, III, or IV), or on the x-axis or y- 6 axis.  Large graphing overheads are provided for projection purposes. Use one of these or a hand-drawn graph on the board to plot these example points: , , , , ,
