Plotting Points

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).

Front

What does the x-coordinate represent in an ordered pair?

Back

The x-coordinate represents the horizontal position of a point on the Cartesian plane.

Front

What does the y-coordinate represent in an ordered pair?

Back

The y-coordinate represents the vertical position of a point on the Cartesian plane.

Front

What is the name of the horizontal number line in a coordinate system?

Back

The horizontal number line is called the x-axis.

Front

What is the name of the vertical number line in a coordinate system?

Back

The vertical number line is called the y-axis.

Front

How do you plot the point (3, 5) on a coordinate plane?

Back

To plot the point (3, 5), move 3 units to the right on the x-axis and 5 units up on the y-axis.

Front

What is the significance of the order of numbers in an ordered pair?

Back

The order of numbers in an ordered pair is significant because it determines the exact location of the point in the coordinate system.

Front

What is the origin in a coordinate plane?

Back

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

Front

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

Back

To identify the coordinates of a point on a graph, find the horizontal position (x-coordinate) and the vertical position (y-coordinate) of the point.

Front

What is the distance between the points (2, 3) and (2, 7)?

Back

The distance between the points (2, 3) and (2, 7) is 4 units, measured vertically along the y-axis.
