Graph on the Coordinate Plane

To graph an ordered pair, draw a dot at the point that corresponds to the coordinates.

Example 1 Graph Point B at (5, 4).

Step 1

Step 2 Step 3

Start at the origin. The x-coordinate is 5, so move 5 units to the right.

Since the y-coordinate is 4, move 4 units up.

Draw a dot. Label the dot B.

Example 2 Graph Point C at (-3 -1, -1).

Step 1 Step 2

Use the coordinate plane shown above. Start at the origin. The x-coordinate is -3-12, so move 3-12 units to the left. Since the y-coordinate is -1, move 1 unit down.

Step 3

Draw a dot. Label the dot C.

Exercises Graph and label each point on the coordinate plane at the right.
