Plane
A plane where a horizontal and vertical number line intersect one another.
How many quadrants are there on a cartesian plane?
4
What is a coordinate on the cartesian plane made up of?
Two numbers. One x coordinate and one y coordinate.
Which number is the x coordinate in (5, 0)?

Can a cartesian plane be left blank with no numbers?
No. A cartesian plane must have numbers to indicate the location of the point.

Can coordinates be a fraction?
Yes. For example: (1/2, 3), (5, 1/4).
Note: We will most likely not be using fractions during this topic.
What do the arrows represent on the x-axis and y-axis represent?
The number plane is endless, there is no limit on the positive or negative numbers.
