The Coordinate Plane Section 1.8

Length of a Segment (Vertical or Horizontal)

The Distance Formula The distance between 2 points A(x1, y1) and B(x2, y2) is:

The Distance Formula AB = 5, and point A has coordinates (1, 2). If the x coordinate of B is 5, what are the possible y values?

The Midpoint Formula The coordinates of the midpoint M of AB with endpoints A(x1, y1) and B(x2, y2) are:

The Midpoint Formula The coordinates of the midpoint M are (-1, 3). If the coordinates of A are (-5, 4) find the coordinates of B.

Recap To find the length of a segment or the distance between 2 points on the coordinate plane, use the Distance Formula. To find the midpoint of a segment, use the Midpoint Formula. If a segment is bisected, it is bisected at its midpoint.
