Hi how can I plot a plane in 3D with given the equation 2x+5y-3z=1?
The answer is as clear as the question. Type the equation 2x+5y-3z=1 in the input bar and the plane will appear in the 3D View.
A couple of extra words after Chris' suggestion.
If your plane has not the z variable in its equation, and if your 3D view is not open, you will see its graphical representation as a line in the Cartesian plane.
So, please open the 3D View before typing an equation of a plane that doesn't contain the z variable, or enter its equation using a "fake" z, that is e.g. 2x + 5y + 0z =1.
There are also commands and tools that allow you to create planes: please see e.g. https://wiki.geogebra.org/e...
