If you mean 3x+2y = -5 and -2x+3y = -5 then they are straight line equations
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: y = 2x and 2y = -x+4 then they are positive and negative straight line equations
It is not one, but they are two perpendicular lines.
Straight 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: x+y = 10 and x-y = 6 then y = -x+10 and y = x+6 which means the lines are perpendicular to each other
Those two statements are linear equations, not lines. If the equations are graphed, each one produces a straight line. The lines intersect at the point (-1, -2).
If you mean: y = 2x and 2y = -x+4 then they are positive and negative straight line equations
That depends on the other equation which has not been given but if 2x-3y = 2 then y = 2/3x-2/3
They are parallel lines.
