When comparing data
two planes next to each other
A real-life example of a line and a plane intersecting can be observed when a beam of sunlight (the line) shines through a window (the plane) into a room. The line of sunlight travels in a straight path, while the window represents a flat surface where the light enters the room. The point where the sunlight hits the floor or any object inside the room marks the intersection of the line and the plane.

two planes next to each other
A complex number, in my life, is a number which is composed of two parts: one part which is a real number and the other which is imaginary. It can be represented by a point in a coordinate plane.
On a coordinate plane, d^2=(y2-y1)^2+(x2-x1)^2 In a real life application d=speed x time
Real life is a real life example!
In building construction, you usually have one horizontal plane (that floors) that is intersected by a vertical plane (the walls or support beams).
The coordinate plane has helped people create graphs. With out graphs, we wouldn't be able to track stocks or display/compare information. The coordinate plane has also been a foundation for maps. The coordinate plane goes by (x,y), where a map goes by (letter, number) or (latitude, longitude). The coordinate plane is the reason we can find where a place is on the map. Because of this, satellites can also show us where we are on a gps and we can get directions via sateliite. The coordinate plane plays a big impact on our life.

Well, there's always the map. Latitude, Longitude.
