Plotting points

Front

What is an ordered pair in coordinate geometry?

Back

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

Front

How do you plot a point given its ordered pair (x, y)?

Back

To plot a point given its ordered pair (x, y), start at the origin (0, 0) on a Cartesian plane. Move 'x' units along the horizontal axis (right for positive, left for negative), and then move 'y' units along the vertical axis (up for positive, down for negative). Mark the point.

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 significance of the origin in a coordinate plane?

Back

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

Front

How can you determine the letter associated with a specific ordered pair?

Back

To determine the letter associated with a specific ordered pair, you need a predefined mapping of letters to coordinates. For example, if (5, 4) corresponds to 'M', then that is the letter for that point.

Front

What is the coordinate of point E if it is located at (5, 2)?

Back

The coordinate of point E is (5, 2), which indicates its position on the Cartesian plane.

Front

What is the ordered pair for the letter K if it is located at (1, -7)?

Back

The ordered pair for the letter K is (1, -7), indicating its position on the Cartesian plane.

Front

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

Back

To identify the coordinates of a point on a graph, locate the point on the Cartesian plane, then read the x-coordinate from the horizontal axis and the y-coordinate from the vertical axis.

Front

What is the relationship between ordered pairs and points on a graph?

Back

Ordered pairs represent the exact location of points on a graph, with the first number indicating the horizontal position and the second number indicating the vertical position.
