Plotting Ordered Pairs

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).

Front

What does the first number in an ordered pair represent?

Back

The first number in an ordered pair represents the x-coordinate, which indicates the horizontal position on the coordinate plane.

Front

What does the second number in an ordered pair represent?

Back

The second number in an ordered pair represents the y-coordinate, which indicates the vertical position on the coordinate plane.

Front

In which quadrant is the ordered pair (2, 5) located?

Back

Quadrant I, where both x and y values are positive.

Front

What is the y-value in the ordered pair (4, 7)?

Back

The y-value is 7.

Front

What is the x-value in the ordered pair (4, 7)?

Back

The x-value is 4.

Front

What is the ordered pair for point E if it is located at (5, 2)?

Back

The ordered pair for point E is (5, 2).

Front

How do you identify the quadrant of an ordered pair?

Back

To identify the quadrant, check the signs of the x and y coordinates: Quadrant I (positive, positive), Quadrant II (negative, positive), Quadrant III (negative, negative), Quadrant IV (positive, negative).

Front

What is the significance of the origin in a coordinate plane?

Back

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

Front

If a point is located at (-3, 4), in which quadrant is it located?

Back

Quadrant II, where x is negative and y is positive.
