Comparing 3 Points on a 3D Graph

[ineedhelpnow]

excuse my TERRIBLE drawing but roughly, is this drawing a good representation of the points?
A(-4,0,-1)
B(3,1,-5)
C(2,4,6)

in my drawing i have the axis as 2, 4, 6 etc

That looks basically correct to me. But it would help if you would put arrows on the tips of the axes to indicate which direction is positive. Alternatively, label the tick points on the axes with 2,4,6,-2,-4,... .

Logically, the locations of the labels of the axes should identify the positive directions.
However, it appears you have treated the x-axis as being negative towards its label.
If that is what you intended, it's an unusual choice.
It makes your coordinate system a left-handed one.
See for instance this wiki article that explains why a right-handed system is preferred.

Anyway, with that choice your points are located correctly.

I thought that I had checked that. But you are correct, the diagram shows a left-handed coordinate system, which goes against the usual convention.

its not like that in my actual drawing by hand. i have no idea why i did it like that on here lol
