A
coordinate plane
is
formed when two
number lines intersect at
their zero points.
Sep 262:31 PM
This intersection is called the
origin
.
The vertical number line is called
the yaxis.
The horizontal number line is called the
xaxis
.

When creating a graph, make sure to
include the following components:
Don't forget to include a scale on both axes!!

What is an
ordered pair?
How are they written?
Mar 75:00 PM
An ordered pair is a
pair of numbers,
written as (x, y),
that represents a
point on the
Cartesian plane.
Sep 262:40 PM
PULL
To graph an ordered pair, move along
the
xaxis
until you reach the number.
Then move up the
yaxis
until you reach
the number.
Draw the point at the intersection of the
two lines.
