:plane
What it looks like: The Cartesian coordinate plane is a vertical line (the y axis) running through a horizontal line (the x axis). It forms a cross which divides the grid that it's placed on into four quadrants. The quadrants are labeled 1, 2, 3, and 4, in counterclockwise direction, starting in the upper right corner. The point where the x and y axis meet, (0,0) is called the origin. You can graph points on the line by counting the amount of points in the first number of the coordinate (x) on the x axis, and then the second on the y. For example, the coordinate (1,2) would be one space to the right and two up.
What it's used for: You use the coordinate plane to graph points, lines (a collection of consecutive points), or functions (an equation leading to a set of points or a set of points both of which don't have the same x coordinate [basically, if you run a vertical line through whatever shape or collection of points you have, and it doesn't touch any two points at the same time, it's a function.])
They are the coordinates.

Yes
1.Finding the solution to a system of linear equations can be found using cartesian coordinates. 2. Graph a circle and you can find the radius using cartesian coordinates.
It is the Cartesian plane or grid system whereas coordinates of x and y are plotted on it.
The Cartesian plane coordinates
Renee Descartes invented the Cartesian Coordinate system, commonly known as rectangular coordinates.
You do not have to. You could use polar coordinates, if you prefer.
The cartesian coordinates are plotted on the cartesian plane
The Cartesian coordinates of the vector represented by the keyword "r vector" are the x, y, and z components of the vector in a three-dimensional coordinate system.
The endpoints of a line segment graphed on a Cartesian coordinate system are (2, -5) and (-4, 2). What are the coordinates of the midpoint of the segment?
You do not have 3 coordinates in the Cartesian plane. The Cartesian plane is a plane and is therefore 2 dimensional. In 2 dimensional space you require only 2 coordinates. 3 coordinates are required to locate a point in 3-dimensional space but then it cannot be a Cartesian PLANE.
