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).
Yes, they are.
It was Rene Decartes
There is no "the" since there are infinitely many non-parallel planes. Two non-parallel planes are planes that intersect in a line.
it is when you go to a career and you learn about cordinate planes
A map is a good example.
architects use coordinate planes to graph where they want the rooms to be

a coordinate plane:)
The coordinate axes are labelled with Indo-Arabic numerals so, to avoid confusion, Roman numerals are used for whole planes.
Engineers uses the coordinate planes all the time. When you take higher engineering course you need to be extremely familiar and good at using coordinate planes in 3 dimensions. Architects use them to make designs and graphs of their model or building.
The axes of coordinate planes intersect at the point of origin.
the opposite?
That's O, the origin, by definition.
