Lets just take the example of having two equations with two unknowns. http://www.wolframalpha.com/input/?i=graph+x-3+y+%3D+2%2C+3+x-4+y+%3D+0

ok but how is it found ?

anonymous · Answer

The point of intersection is how you solve a linear system of equations.  You can verify this by solving for x and y and then you would then see that if you plotted that x and y it would be that very point of intersection.

Does that make sense?
