Terms - The Cartesian Plane Flashcards
The horizontal directed line is called the ____.
x-axis
What is the Cartesian Plane?
A systematic link between geometry and algebra that is two dimensional. This consists of 2 directed lines (a.k.a. 2 number lines) that perpendicularly intersect their zero points.
The vertical directed line is called the ___.
y-axis
What is the “origin?”
The origin is the point of intersection of the x and y axes; this is denoted by uppercase O.
What are the positions of any point on the Cartesian Plane called?
They are called “coordinates.”
What is the horizontal coordinate called?
x-coordinate
What is the vertical coordinate called?
y-coordinate
True or False: The Cartesian Plane is divided in quadrants.
This is true. The order starts with the upper right corner of the diagram and continues counterclockwise.
What belongs on Quadrant I?
All quadrants have both x and y coordinates. In Quadrant I, the x-coordinate and y-coordinate are positive.
What belongs on Quadrant II?
The x-coordinate is negative while the y-coordinate is positive.
What belongs on Quadrant III?
Both x and y are negative.
What belongs on Quadrant IV?
The x-coordinate is positive but the y-coordinate is negative.
