Cartesian 3D Vector Plotting Points?

[Stanc]

Homework Statement

Plot the following point:
B(-2,3,5)

The Attempt at a Solution

If I were to plot (-2,3,5), when I make my first movement of -2, it does not move anywhere on the y-axis correct and when I am moving on my Y axis, There is no movement in the z axis?

In Cartesian coordinates (-2,3,5) is the same thing as saying "-2 in the x-direction, 3 in the y-direction, and 5 in the z-direction". As movement in the x,y,z-directions don't affect the other directions, so yeah...although note that if you're moving on the y-axis, you're not only not moving on the z-axis, but you're also not moving on the x-axis.

So it's "move -2 on the x-axis, move 3 on the y-axis, move 5 on the z-axis".

Ok thank you, can you give me some help on this:

What is the axis or plane these points would lie:

(-3,0,0) (4,-2,0) and (0,3,-5)

If you're unsure about how to plot a point in 3D space, I'm not too sure how I'm going to explain to you how to find the equation of a plane from three points.

Open your calc 3 book and get to reading.

The way I would do it is find a normal vector for the plane by taking a cross product of two vectors defined by those points and then dotting that normal vector with a vector in the plane and setting it to zero...

You need to go and learn the material. The answer is 10x + 35y + 27z + 30 = 0, if you need to check yourself.
