• Graph rational numbers on the coordinate
plane and use the coordinate plane to
represent relations.

Name an Ordered Pair
Name the ordered pair for
point A.
●
Start at the origin.
●
Move right to find the
x-coordinate of Point A,
which is 2.
●
Move up to find the
y-coordinate, which is

Relations as Tables and Graphs
Express the relation {(4, 2), (6, –1), (5, –3), (–2, –3)}
as a table and a graph. Then state the domain and
range.
Place the ordered pairs in a table with x-coordinates
in the first column and the y-coordinates in the
second column.
Relations as Tables and Graphs
Graph the ordered pairs on a coordinate plane.
Answer: The domain is {–2, 4, 5, 6}.
The range is {–3, –1, 2}.
State the domain and range of the relation
{(3, 5), (–4, 0), (2, –8), (6, 1)}.
A. domain: {–4, 2, 3, 6}; range: {–8, 0, 1, 5}
B. domain: {2, 3, 4, 6}; range: {0, 1, 5, 8}
C. domain: {–8, 0, 1, 5}; range: {–4, 2, 3, 6}
D. domain: {3, –4, 2, 6}; range: {5, –8, 1}

A. PIES Mike is buying pies for a party. The price
for 1 pie is $4.
Make a table of ordered pairs in which the
x-coordinate represents the number of pies and
the y-coordinate represents the total cost for
2, 3, 4, and 5 pies.
