The Coordinate Plane

Front

How do you correctly write an ordered pair?

Back

An ordered pair is written as (x, y), where x is the value on the x-axis and y is the value on the y-axis.

Front

The Y axis is _______?

Back

The Y axis is vertical.

Front

The coordinate plane is divided by a horizontal number line called what?

Back

The horizontal number line is called the x-axis.

Front

Give the coordinates for point H.

Back

The coordinates for point H are (1, 2).

Front

Which quadrant contains the point named by (2, 5)?

Back

The point (2, 5) is in Quadrant I.

Front

What is the origin in the coordinate plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect.

Front

What are the four quadrants in the coordinate plane?

Back

Quadrant I (x positive, y positive), Quadrant II (x negative, y positive), Quadrant III (x negative, y negative), Quadrant IV (x positive, y negative).

Front

What does the x-axis represent?

Back

The x-axis represents the horizontal number line in the coordinate plane.

Front

What does the y-axis represent?

Back

The y-axis represents the vertical number line in the coordinate plane.

Front

How do you identify the quadrant of a point?

Back

To identify the quadrant, look at the signs of the x and y coordinates: (+,+) for Quadrant I, (-,+) for Quadrant II, (-,-) for Quadrant III, and (+,-) for Quadrant IV.
