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

What are the coordinates of point K?

Back

(3, -3)

Front

Which point corresponds to the coordinates (-1, 1)?

Back

Point J.

Front

What is the domain of a relation?

Back

The domain of a relation is the set of all possible input values (x-coordinates) for the ordered pairs in the relation.

Front

Given the relation {(1,3), (5,15), (2,6), (4,12), (3,9)}, what are the domain values?

Back

{1, 2, 3, 4, 5}

Front

What is the range of a relation?

Back

The range of a relation is the set of all possible output values (y-coordinates) for the ordered pairs in the relation.

Front

Given the relation {(1,3), (5,15), (2,6), (4,12), (3,9)}, what are the range values?

Back

{3, 6, 9, 12, 15}

Front

How do you determine the domain from a set of ordered pairs?

Back

To determine the domain, list all the unique x-coordinates from the ordered pairs.

Front

How do you determine the range from a set of ordered pairs?

Back

To determine the range, list all the unique y-coordinates from the ordered pairs.

Front

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

Back

The order in an ordered pair is significant because it indicates the position of the point in the coordinate system; the first number represents the x-coordinate and the second number represents the y-coordinate.
