Plotting in 3-D Section 7.1.1

Learning Targets Visualize points in a 3-D coordinate system Give the coordinates of points in a 3-D coordinate system

Up To Now… Only graphed or plotted on 1-D or 2-D coordinate systems Single variable equations and points are plotted on a 1-D number line Two variable equations and points are plotted on 2-D coordinate systems Ex: 3x=15 (Single Variable Equation) Ex: y = 3x + 5 (Two Variable Equation) Ex: (3,4) (Point in a 2-D coordinate system)

What is the Difference Drawing Dimensions

Construct a 3-D Coordinate System Use the cut-out to construct a coordinate system

Labeling Points Where is the point x=3, y=2, z=1? How do you propose we write the coordinates for this point or any point in a 3-D system? (3,2,1) y x z

Practice I am going to roll the dice and get three points. I want you to write the coordinate’s for this point and locate where it is in the 3-D coordinate system
