Definitions • Ordered Pairs – a set of “x” and “y” coordinates written in the form (x1, y1) • Coordinate Plane – a graph composed of the x-axis and y-axis that intersect at the origin (0,0). The plane is divided into four quadrants.
Coordinate Plane The y-axis is the vertical number line. Quadrant I Quadrant II The x-axis is the horizontal number line. Origin Quadrant III Quadrant IV
Ordered Pair • An ordered pair is a pair of numbers, such as (-3, 2) used to locate a point in the coordinate plane. H 2 is the y coordinate H (-3, 2) -3 is the x coordinate
Graphing and Identifying Ordered Pairs P • Graph the Ordered Pair. • A (4, 3) • B (-1, -2) • C (3, -4) • Write the Ordered Pair. • P • V • W A V B W C (1, 6) (5, 0) (-5, -4)
