Coordinate Plane and Patterns

In an ordered pair, the _________ number is called the y-coordinate.

• first

• second

• both

• neither

To graph the point (5, 9) on the coordinate plane, start at the origin. Move 5 units _______ and 9 units _______.

• right... down

• left... up

• right... up

• left.... down

Start at the origin. Move 3 units right and 1 unit up.

What is the ordered pair for this point?

• (4, 3)

• (1, 3)

• (3, 4)

• (3, 1)

A point is plotted on the coordinate plane.

Which ordered pair represents a point 3 units closer to the x-axis and 2 units farther from the y-axis?

• (3, 7)

• (6, 5)

• (5, 4)

• (4, 5)

The first few numbers in two patterns are shown in the table. Both patterns will continue. Which statement correctly compares the numbers in each row?

• The y coordinates are 3 more than the x coordinates.

• The y coordinates are 4 more than the x coordinates.

• The y coordinates are 4 times more than the x coordinates.

• The y coordinates are 3 times more than the x coordinates.

Brandon and Amiya make number patterns. -Brandon's number pattern begins with 640 and uses the rule of dividing by 2. -Amiya's number pattern begins with 30 and uses the rule of adding 15. Let x represent Brandon's number and y represent Amiya's number. Which ordered pairs show the first four numbers in each of their patterns?

• (30, 640), (45, 320), (60, 160), (75, 80), (90, 40)

• (640, 30), (320, 45), (160, 60), (80, 75)

• (30, 640), (45, 340), (60, 170), (85, 80), (80, 40)

• (640, 30), (320, 45), (160, 50), (80, 65)
