Five-Minute Check (over Lesson 2–2)
Main Idea and Vocabulary
Key Concept: Coordinate Plane
Example 1:Naming Points Using Ordered Pairs
Example 2:Graph an Ordered Pair
Example 3:Locate an Ordered Pair
Example 4:Identify Quadrants
• coordinate plane
• x-axis
• y-axis
• origin
• quadrant
• Graph points on a coordinate plane.
• ordered pair
• x-coordinate
• y-coordinate
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.

Write the ordered pair that names point M. Then name the quadrant in which the point is located.
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.
