7. Example 1 Naming Points Using Ordered Pairs Write the ordered pair that names point R. Then state the quadrant in which the point is located. Start at the origin. Answer: So, the ordered pair for point R is (–2, 4). Point R is located in Quadrant II. Move left on the x-axis to find the x-coordinate of point R, which is –2. Move up to find the y-coordinate, which is 4.

9. Example 2 Graph an Ordered Pair Graph and label point M(3, 5). Answer: Start at the origin. The x-coordinate is 3. So, move 3 units to the right. Draw a dot and label it M(3, 5). Next, since the y-coordinate is 5, move 5 units up.
