Graphing ordered pairs

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, written in the form (x, y), where 'x' is the horizontal coordinate and 'y' is the vertical coordinate.

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 of the point 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 of the point on the graph.

Front

How do you plot the point (3, 2) on a graph?

Back

To plot the point (3, 2), start at the origin (0, 0), move 3 units to the right (positive x-direction), and then move 2 units up (positive y-direction).

Front

What is the location of point E if its ordered pair is (5, 2)?

Back

Point E is located 5 units to the right and 2 units up from the origin on the graph.

Front

What is the location of point H if its ordered pair is (3, -2)?

Back

Point H is located 3 units to the right and 2 units down from the origin on the graph.

Front

What is the ordered pair for point F if it is located at (3, 0)?

Back

The ordered pair for point F is (3, 0), meaning it is 3 units to the right of the origin and on the x-axis.

Front

What is the ordered pair for point B if it is located at (-3, 0)?

Back

The ordered pair for point B is (-3, 0), meaning it is 3 units to the left of the origin and on the x-axis.

Front

How do you identify the coordinates of a point on a graph?

Back

To identify the coordinates of a point, find its horizontal position (x-coordinate) and vertical position (y-coordinate) relative to the origin.

Front

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

Back

The origin is the point (0, 0) on a graph where the x-axis and y-axis intersect, serving as the reference point for all other points.
