Mass Energy.
A linear equation.
The equation E=mc^2 relates to the equivalence of mass and energy, showing that a small amount of mass can be converted into a large amount of energy. This is a key concept in understanding nuclear reactions and the energy release in processes such as nuclear fission and fusion.
A straight line equation
Einstein's most famous equation, E=MC2 (Energy=Mass x Speed of Light (in a vacuum) Squared) is the equation for Mass-Energy equivalence, which is that the mass of a body is equal to its energy content. It is the core basis for obtaining a nuclear reaction.

"y x 2 2x -3 is not any kind of equation because it does not have an equals sign (=).
Its kind of hard to draw a graph in pure text... Try plugging your equation into www.wolframalpha.com/ ;)
It seems to be some kind of simultaneous equation with too many equality signs in it.
That would be called mass energy, or total internal energy.
A Diophantine Equation. In order to solve it, you should use Euclide's algorithm.
