Graphing Ordered Pairs

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent 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 graph.

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 graph.

Front

What is the origin in a coordinate plane?

Back

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

Front

How do you identify the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in the ordered pair, written as (x, y).

Front

How do you identify the y-coordinate in an ordered pair?

Back

The y-coordinate is the second number in the ordered pair, written as (x, y).

Front

What is the significance of the point (0, 0)?

Back

The point (0, 0) is known as the origin and serves as the reference point for all other points on the coordinate plane.

Front

How do you plot the point (3, 4) on a graph?

Back

To plot (3, 4), move 3 units to the right on the x-axis and 4 units up on the y-axis.

Front

What is the coordinate of a point located 5 units left and 2 units down from the origin?

Back

The coordinate would be (-5, -2).

Front

What is the relationship between ordered pairs and the Cartesian plane?

Back

Ordered pairs are used to locate points on the Cartesian plane, which consists of a horizontal x-axis and a vertical y-axis.
