Intro to 3-D graphing

1. 11.1 The Three-
Dimensional Coordinate
System
Objective: Graph three dimensional
points and find the distance and
midpoint between them.
Standard: Linear Algebra 7.0

2. Space…the final frontier…

3. Octants
Octant I Octant II Octant III Octant IV
Octant V Octant VI Octant VII Octant VIII

4. Graphing Points
Ex. 1) Graph the following
points.
A(-2, 5, -3)
B(4, 0, -2)

5. Distance Between Two Points in
Space

6. Ex. 2) Find the distance between the
points (-4, 7, 0) and (6, -2, 9).

7. Midpoint

8. Ex. 3) Find the midpoint between the
points (-4, 7, 0) and (6, -2, 9).

9. Whiteboards
Find the distance and midpoint between the
two points (4, -3, 5) and (-2, 5, -8).
