Lesson: Coordinate Plane
Also called the 'Cartesian' Plane)

One of the major parts of math
is the coordinate plane.
The coordinate plane has
3 main parts
x-axis
y-axis
origin
The coordinate plane has
3 main parts
a thick horizontal line
the x-axis is
represented by 
x-axis
y-axis
origin
The coordinate plane has
3 main parts
x-axis
a thick horizontal line
the x-axis is
represented by 
x-axis
y-axis
origin
The coordinate plane has
3 main parts
the y-axis is
x-axis
y-axis
origin
The coordinate plane has
3 main parts
a thick vertical line
the y-axis is
represented by 
x-axis
y-axis
origin
The coordinate plane has
3 main parts
y-axis
a thick vertical line
the y-axis is
represented by 
x-axis
y-axis
origin
The coordinate plane has
3 main parts
the origin is
where the x-axis
and the y-axis
meet
x-axis
y-axis
origin
The coordinate plane has
x-axis
?
3 main parts
origin
?
the origin is
where the x-axis
and the y-axis
meet
y-axis
?
