Answer:
Rectangular Coordinate System
The rectangular coordinate system consists of two real number lines that intersect at a right angle. The horizontal number line is called the
x-axis, and the vertical number line is called the
y-axis. These two number lines define a flat surface called a plane, and each point on this plane is associated with an ordered pair of real numbers
(x,y). The first number is called the
x-coordinate, and the second number is called the
y-coordinate. The intersection of the two axes is known as the origin, which corresponds to the point
(0,0).
