Question

Describe the location of point (−5, −5, 5) in three-dimensional coordinate space.

Answer 1

Here's a really cool website that let's you input 3D points!

From the attached picture you can see that the point has moved back 5 units, to the left 5 units, and up 5 units.

Answer 2

Answer:

Option B is right

Step-by-step explanation:

In 3 dimension we have 8 octants, with x,y, z axes mutually perpendicular.

Given coordinate is (-5,-5,5)

Since x is negative we find move 5 units back first,

y is also negative hence move 5 units left

Z is positive this implies 5 units up

In two dimension we do as follows:

Locate x on the x-axis.

From that point, moving parallel to the y-axis, move y units. This is your point.

IN three dimension we extend as follows:

Locate x on the x-axis.

From that point, moving parallel to the y-axis, move y units.

From that point, moving parallel to the z-axis, move z units. This is your point
