This is called a Cartesian coordinate system, which is named for the French mathematician and philosopher René Descartes (1596-1650).
The origin is where the two intersect. This is where both number lines are 0.
one solution; the lines that represent the equations intersect an infinite number of solution; the lines coincide, or no solution; the lines are parallel
a coordinate plane
Perpendicular lines form right angles when they intersect.
Graphically, it is the point of intersection where the lines (in a linear system) intersect. If you have 2 equations and two unknowns, then you have a 2 lines in a plane. The (x,y) coordinates of the point where the 2 lines intersect represent the values which satisfies both equations. If there are 3 equations and 3 unknowns, then you have lines in 3 dimensional space. If all 3 lines intersect at a point then there is a solution to the system. With more than 3 variables, it is difficult to visualize more dimensions, though.
they are perpendicular.
They do not. A set of lines can also be considered as a system of linear equations. But the fact that there is such a system does not mean that the lines intersect.

Zero; parallel lines never intersect.
This is False the correct definition is this: The number lines that form a Cartesian coordinate system are called the axes and the point where they intersect is called the origin.
If the lines intersect, then the intersection point is the solution of the system. If the lines coincide, then there are infinite number of the solutions for the system. If the lines are parallel, there is no solution for the system.
