Objective :Objective Uses all four quadrants of the coordinate plane to:
Identify the ordered pairs
Plot the ordered pairs
Understanding theCoordinate Plane :Understanding theCoordinate Plane This is the X axis. This is the Y axis. Quadrant II Quadrant III Quadrant IV Quadrant I The (0,0) point is called the origin.
Write the coordinates for each point. :Write the coordinates for each point. H

(-6,-5)
(9,-8)
Find each ordered pair. Write the letter for the point named by the ordered pair. :Find each ordered pair. Write the letter for the point named by the ordered pair. (-6, 0)

Slide 7:When identifying ordered pairs on a graph, the x value comes first, then the y value.
Example: D = (3, -2)
Organizing Integer Data :Organizing Integer Data When plotting ordered pairs, always start from
(0, 0). This point is called the origin.
When plotting ordered pairs, always move along the X axis, then move along the Y axis. Plot: B = (2, -3)
