Given the following point:
(3, -1, -1)
Let's plot.
The given coordinates are in three dimensions, (x, y and z). Thus we get,
x = 3
y = -1
z = -1
Let's first plot the 2-dimensional coordinates which are the x and y: 3,-1.
We get,
From there, we next apply the third dimension which is z at -1.
Thus, at the given perspective, the plot for (-1, 6, -1) will be:
