Coordinate Plane
When comparing data
A Cartesian coordinate plane system specifies each point uniquely in a plane by a pair of numerical coordinates. These coordinates are the signed distances from the point to two fixed perpendicular directed lines often called the x and y axis. The measurements on the axes are same units of length. The use of x and y to name is axes is common, but there are many other ways to name them.
To graph points on a graph, typically for Algebra or Geometry. :)
Usually the first quadrant.

You use the distance formula.

The North American Datum of 1983 (NAD83), which is defined in metres, replaced The NAD27 in the 1980s. The State Plane Coordinate Systems were also updated, but the National Geodetic Survey left the individual states to decide which (if any) definition of the foot they would use. All State Plane Coordinate Systems are defined in meters, and 42 of the 50 states use the meter-based State Plane Coordinate Systems only.
Yes, almost all the time. And when it is not coordinate planes it is coordinate hype-spaces (more than just the 2 dimensions that the coordinate plane allows).
We assign coordinates to point on the plane and use those coordinates to tell us about the points. For example, the distance formula tells us how far apart they are, the midpoint formula tells us where there midpoint is. All of these and much more depend looking at a point as an ordered pair, (x,y) in the coordinate plane.The coordinate system is determined by the two directed lines and the given unit length. When the directed lines intersect at a right angle, the system is Cartesian, and (x,y) are Cartesian coordinates of the point. Normally, x-axis and y-axis are chosen so that an anticlockwise rotation of one right angle takes the positive x-direction to the positive y-direction. There are other methods of assigning coordinates to points in the plane. one such is the method of polar coordinates. The coordinate plane is the main idea in analytic geometry.
To work out a coordinate when there are no numbers on either the X or Y axis begin by drawing a vertical line down from the point of interest and have it cross the horizontal axis. Where the two meet label it as X and then use a ruler to measure from the 0 point to the X. This will give you the X axis coordinate. Repeat the process to find the Y coordinate but draw a horizontal line from the point of interest instead of a vertical line.
