##### System of Reference Axes

Before introducing the concept of the reference axis system, we will recall the concept of the real line and locate some points on the real line as shown in the figure below, also remember that the real number system consists of both rational and irrational numbers, which we can write the set of real numbers as the union rational and irrational numbers.

##### The intersection of two Planes

If two planes are not parallel, then they intersect and their point of intersection is a straight line. Thus, two non-parallel planes represent a line given by two simultaneous linear equations in x, y, and z, and are known as nonsymmetric forms of the equations of the line.

##### Rectangular coordinates for three dimensions:

Because you know that the position of any point in three dimensions can be obtained by three mutually perpendicular lines known as the x, y, and z axes and also shown in the figure below. These coordinate axes are known as the rectangular coordinate system.
