architects use coordinate planes to graph where they want the rooms to be
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.
yes
It was Rene Decartes
a coordinate plane:)
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.
That's O, the origin, by definition.
A map is a good example.
Think about it, the x & y planes intersect and what one number has both, the x & y planes intersect. 0 on the coordinate plane is the, origin.
