DISTANCE OF A SEGMENT ON A COORDINATE PLANE

The Distance Formula: The distance between points (x1,y1) and (x2,y2) is given by the formula Note: This is really the Pythagorean Theorem in a different form.
  1. Plot the points (0,0) and (-4,3).
  2. Connect the points using the line segment.

3. What is the distance of the two points?

MIDPOINT ON A COORDINATE PLANE

To find the midpoint of a segment on a coordinate plane, find the average of your x and the average of your y values.
  1. Plot the points (-1,-3) and (3, 2).
  2. Connect the points with a segment and find the midpoint.

What were the coordinates of the midpoint you calculated above?

OTHER ENDPOINT ON A COORDINATE PLANE

  1. Plot the points A(-3, -1) and M(-1,2). 
  2. Connect the points with a segment and find the midpoint.
  3. Find the coordinates of the missing endpoint if M is the midpoint of AB.

What are the coordinates of the missing endpoint?
