Naming Points Using Ordered Pairs
Write the ordered pair that names point S.
Step 1 Start at the origin. Move right along the x-axis
until you are under point S. The x-coordinate
of the ordered pair is 1.
Answer: Point S is named by the ordered pair (1, 2).
Step 2 Now move up until you
reach point S. The y-coordinate is 2.

Graphing Ordered Pairs
Graph the point T(2, 2).
• Start at the origin.
• Move 2 units to the right on the x-axis.
Answer:
• Then move 2 units up to locate the point.
• Draw a dot and label the dot T.

• The value is halfway between 1 and 2. So, on the
x-axis, move to the right halfway between 1 and 2.
Graphing Ordered Pairs
• Start at the origin.
Answer:
• Move 0 units up on the y-axis.

Graphing Ordered Pairs
Graph the point V(0.5, 1).
• Start at the origin.
• The value 0.5 is halfway between 0 and 1. So, on the x-axis, move halfway between 0 and 1.
Answer:
• Then move 1 unit up to locate the point.
• Draw a dot and label the dot V.

List Data as Ordered Pairs
PETS Amelia feeds her dog, Buster, 2 cups of food each day. Amelia made this table to show how much food Buster eats for 1, 2, 3, and 4 days. List this information as ordered pairs (days, food).
Answer: The ordered pairs are (1, 2), (2, 4), (3, 6), and (4, 8).
