Plotting and Identifying Points

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a two-dimensional space, 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 position along the horizontal axis.

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 position along the vertical axis.

Front

How do you plot the point (3, 0) on a coordinate plane?

Back

To plot the point (3, 0), start at the origin (0, 0), move 3 units to the right along the x-axis, and then 0 units up or down on the y-axis.

Front

What is the ordered pair for point L if it is located at (-4, -4)?

Back

The ordered pair for point L is (-4, -4).

Front

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

Back

To identify the coordinates of a point, find its position relative to the x-axis (horizontal) and y-axis (vertical) and express it as (x, y).

Front

What is the significance of the x-axis in a coordinate plane?

Back

The x-axis is the horizontal line in a coordinate plane where the y-coordinate is zero.

Front

What is the significance of the y-axis in a coordinate plane?

Back

The y-axis is the vertical line in a coordinate plane where the x-coordinate is zero.

Front

If a point is located at (1, -7), what letter corresponds to that point?

Back

The letter corresponding to the point (1, -7) is K.

Front

What is the correct order of coordinates in an ordered pair?

Back

The correct order is (x, y), where x is the first value and y is the second value.
