Math 1021 Section 2.1 Rectangular Coordinates The rectangular or Cartesian coordinate system consists of the x-axis, the y-axis and the origin. Any point P can be located by using an ordered pair (x, y) of real numbers. Distance Formula: The distance between two points P 1 = (x 1 , y 1 ) and P 2 = (x 2 , y 2 ), denoted by d(P 1 ,P 2 ) is 2 2 1 2 2 1 2 1 ( , ) ( ) ( ) d P P x x y y = - + - The distance formula comes from the Pythagorean theorem. Midpoint Formula: The midpoint M = (x, y) of the line segment from P 1 = (x 1 , y 1 ) to P 2 = (x 2 , y
