Determine the coordinates and state the octant in which each point lies.

Answer to Problem 92E
The coordinate of point A is (6,2,–6) and lies in Octant V.
The coordinate of point B is (2,–1,2) and lies in Octane IV
The coordinate of point C is (–2,3,1) and lies in Octant II
Explanation of Solution
Given:
Consider the given points A,B and C on coordinate axis:
The point A is located six units in front of the yz plane, two units to the right of the xz plane, and six units below the xy plane. Therefore coordinate of point A is (6,2,–6) vand lies in Octant V.
Similarly the point B is located two units in front of the yz plane, one unit to the left of the xz plane, and two units above the xy plane. Therefore coordinate of point B is (2,–1,2) and lies in Octane IV
Similarly the point C is located two units behind the yz plane, three units to the right of the xz plane, and two units above the xy plane. Therefore coordinate of point C is (–2,3,1) and lies in Octant II
