Composition from Ordered Pairs, Tables and Graphs

Meaning of ordered pairs: An ordered pair is a composition of the x coordinate and the y coordinate (ordinate), having two values written in a fixed order within parentheses.

• FALSE

• TRUE

Which of these answer choices is an example of ordered pairs?

(You can choose however many answers as you want)

• (X, Y)

• The ordered pair (0,0) is also known as the origin

• The ordered pair (0,0) is also known as the

  y-axis

• Y represents the second number in an ordered pair

what is the definition of a graph?

• A graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related". The objects correspond to mathematical abstractions called vertices (also called nodes or points) and each of the related pairs of vertices is called an edge (also called link or line).

• A graph is a chart
