Answer:
The rectangular coordinate system. consists of two real number lines that intersect at a right angle. ... These two number lines define a flat surface called a plane flat surface defined by the x- and y-axes., and each point on this plane is associated with an ordered pair. of real numbers (x, y).
Step-by-step explanation:
The distance formula, d=√(x2−x1)2+(y2−y1)2, is derived from the Pythagorean theorem and gives us the distance between any two points, (x1,y1) and (x2,y2), in a rectangular coordinate plane
