Do Now. You have 5 minutes.
1. Draw a coordinate plane.
a. Label the x-axis and number it from 3
to -3
b. Label the y-axis and number it from 3
to -3
c. Label the origin
d. Graph the point (1,3)
e.
Graph the point (-2, 2)

The vertical number line is called the:
The horizontal number line is called the:
The point where the x-axis and the y-axis intersect
is called the:
When you move right on the x-axis the numbers
are:
When you move left on the x-axis the numbers
are:
When you move up on the y-axis the numbers are:
When you move up on the y-axis the numbers are:
The four sections of the Coordinate Plane are
called:
Cold Call Review
Recap: you can graph any point on the
coordinate plane when you have an
ordered pair. Ex. (4, 2)
1. The first number in the ordered pair is the:
2. The second number in the ordered pair is
the:
3. The ordered pair to mark the Origin is
expressed as:
New Material
 Relation:
any set of ordered pairs. Ex. {(3,2), (1,-2),
 Relations
can be represented as a table and as a
(4, -1)}
graph.
 The
domain is the set of x-coordinates.
 The
range is the set of y-coordinates.
Example with New Material:
Express the relation {(2, 6), (-4,-5), (-3,6),
(0,4)} as a table and a graph. Then state
the domain and the range.

Domain is {-4, -3, 0, 2} and the
Range is {-5, -4, 6}

Draw a Coordinate Plane. Label the x-axis
and y-axis and number from 4 to -4 on
both the x-axis and y-axis. MAKE SURE YOU
LEAVE ROOM ON YOUR WHITEBOARD FOR
A TABLE!
Graph and label the following points: (3,
1), (1, -2), (-2, 4) and (-2, -3).
Express the above relation as a table.
Write the domain of the above relation.
Write the range of the above relation.
How will we use this in real life?
Ex. Mike is buying pies for a party. The
price for one pie is $4.
A. 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.
B. Graph the ordered pairs.
Independent Practice
Need
more practice: work through
examples 5 and 6 on pg. 277-278.
Work all parts of these problems.
Feeling confident: work the following
problems: pg. 279: 26 and 28; 34-42
Computer users: first take the Review
Quiz on Brain Pop; after you have
completed this, take the Graded
Quiz. Review your answers and write
down how many you got correct.
Common Core Prep
 Manny
has 5 action DVD's, 4 comedy DVD's, and 7
drama DVD's. A friend borrows one of the drama
DVD's. Manny decides to watch one of his remaining
DVD's. He randomly picks one to watch.
 Step A
 What is the probability that Manny chooses an action
DVD?
 Step B
 Use what you know about probability to explain how
you determined the probability that Manny will
randomly select an action DVD. Use words, numbers,
and/or symbols in your explanation.

Draw a coordinate plane with
the and number both the xaxis from 5 to -5.
Express the following relation
as a table and a graph (using
the coordinate plane you just
drew). {(-4,2), (2,1), (0,3),
(5,3)}. State the domain and
the range.
