Plotting points

Front

What is the definition of an ordered pair?

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 on a Cartesian plane?

Back

To plot a point on a Cartesian plane, start at the origin (0, 0). Move horizontally to the x-coordinate and then vertically to the y-coordinate. Mark the point where these two movements intersect.

Front

What does the point (0, 0) represent on a graph?

Back

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

Front

What is the significance of the x-coordinate in an ordered pair?

Back

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

Front

What is the significance of the y-coordinate in an ordered pair?

Back

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

Front

If a point is located at (3, 2), what does this indicate about its position?

Back

The point (3, 2) is located 3 units to the right of the origin and 2 units up.

Front

How can you determine the location of point B if it is given as (0, 4)?

Back

Point B is located at the intersection of the vertical line at x = 0 and the horizontal line at y = 4.

Front

What is the relationship between the coordinates of a point and its position on the graph?

Back

The coordinates of a point directly determine its position on the graph, with the first number representing the horizontal position and the second number representing the vertical position.

Front

What does it mean if a point has a negative x-coordinate?

Back

A negative x-coordinate indicates that the point is located to the left of the origin on the x-axis.

Front

What does it mean if a point has a negative y-coordinate?

Back

A negative y-coordinate indicates that the point is located below the origin on the y-axis.
