What do you call equations describing two or more lines

No the only time that a system of equations would have no solutions is when the two equations have the same slope but different y-intercepts which would mean that they are parallel lines. However, if they have different slopes and different y-intercepts than the solution would be where the two lines intersect.

2 sets of Parallel lines

Horizontal : y = 0Vertical: x = -2.

They don't, they are parallel to each other.

If you refer to linear equations, graphed as straight lines, two inconsistent equations would result in two parallel lines.

The two equations represent the same straight line.

Without any equality signs the given terms can't be considered to be equations.

If you mean 3x+2y = -5 and -2x+3y = -5 then they are straight line equations

Then they are simultaneous equations.

That they, along with the equations, are invisible!

They are simultaneous equations.

Its called Simultaneous Equations

If you mean: x+y = 10 and x-y = 6 then y = -x+10 and y = x+6 which means the lines are perpendicular to each other

All the lines meet at one point: a single solution. All the lines are the same: infinitely many solutions. At least one of the lines does not pass through the point of intersection of the others: no solution.
