Understanding Ordered Pairs and Coordinate Planes

What is the name of the horizontal line in a coordinate plane?

• y-axis

• w-axis

• z-axis

• x-axis

Where do the x-axis and y-axis intersect on a coordinate plane?

• At the origin

• At the point (1,1)

• At the point (0,1)

• At the point (1,0)

In an ordered pair, which coordinate is listed first?

• x-coordinate

• w-coordinate

• z-coordinate

• y-coordinate

What is the ordered pair for the origin?

• (0,0)

• (0,1)

• (1,1)

• (1,0)

If a point is located at (1,6) on a coordinate plane, how many units is it from the origin along the x-axis?

• 1 unit

• 6 units

• 0 units

• 7 units

For the point (4,2), how many units do you move up from the x-axis?

• 0 units

• 6 units

• 2 units

• 4 units

What is the y-coordinate of the point (9,9)?

• 9

• 0

• 1

• 8

If given the ordered pair (5,8), where would you plot the point on the y-axis?

• At 3

• At 8

• At 5

• At 0

How many units do you move along the x-axis for the point (7,4)?

• 11 units

• 0 units

• 7 units

• 4 units

What is the x-coordinate for the point (10,1)?

• 1

• 10

• 0

• 11
