Invisible lines!
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.
What do you call equations describing two or more lines
That they, along with the equations, are invisible!
They are simultaneous equations.
fossils match up coast lines fit together coal deposits line up faults match up
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
Algebraic equations, trigenometric equations, linear equations, geometric equations, partial differential equations, differential equations, integrals to name a few.
