1. Section 10-4 Graphing Multivariable functions

2. 1. Plot P(3, 5)

3. Three Dimensional Cartesian Coordinate System Z Y X

4. Coordinate Axis The x-axis appears to go from front to back the y-axis from left to right the z-axis from top to bottom The positive x direction is from the origin forward The positive y direction is from the origin right The positive z direction is from the origin up

5. Octants The three axis divide the space into 8 octants. Four above the xy plane and four below the xy plane

6. Octants I.(x, y, z) II.(-x, y z) III.(-x, -y, z) IV.(x, -y, z) V.(x, y -z) VI.(-x, y, -z) VII.(-x, -y, -z) VIII.(x, -y, -z)

9. 3. Graph the plane y = 5 y x z

10. 4. y x z

11. 5. y x z
