I know there is an easy way to plot a point in xyz plane, but I can't remember it now. For example if the point is (3,4,2) you count the squares in the right direction and mark it. Can someone help me with this please?

(3,4,2) = (x,y,z)
x= 3
y= 4
z= 2
X is the coordinate in the horizontal plane
Y is the coordinate in the vertical plan
Z is the coordinate in the 3rd plane visible in a 3D diagram.
To plot the point mark the interception point. Because x is positive and in the horizontal plane count 3 squares right from the origin (0,0). Because y is positive and in the vertical plane count 4 squares up. That is the point (3,4). Plotting a Z coordinate accuately requires graphing software, I believe.
