MATH 100: Precalculus
Graphing and Distance

The purpose of this exercise is to familiarize yourself with plotting points and computing distances on the number line and in the Cartesian plane. You may work in groups of 2 or 3 students on this project; if you get stuck, ask a neighboring group for help!
  1. For each problem, graph the points and find the distance between them.

  2. Give the coordinates of four different points that are exactly 2 units away from the point (3,1) in the Cartesian plane.
