Main Idea/Vocabulary coordinate plane x-axis (horizontal) y-axis (vertical) Origin (0, 0) Quadrant – 1 of 4 sections Graph points on a coordinate plane (2.8.8G) (M7.C.3.1). ordered pair (1, 2) x-coordinate (x, y) y-coordinate (x, y)

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.

1.A 2.B 3.C 4.D Example 1 A.(–3, –1); Quadrant III B.(2, 1); Quadrant I C.(3, 1); Quadrant I D.(3, –1); Quadrant IV Write the ordered pair that names point M. Then name the quadrant in which the point is located.

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.
