Without any equality signs the given terms can't be considered to be equations.
The two equations represent the same straight line.
If you mean 3x+2y = -5 and -2x+3y = -5 then they are straight line equations
x=3
If you mean: y = 2x and 2y = -x+4 then they are positive and negative straight line equations
No.
The two equations represent the same straight line.
If you mean 3x+2y = -5 and -2x+3y = -5 then they are straight line equations
When (the graph of the equations) the two lines intersect. The equations will tell you what the slopes of the lines are, just look at them. If they are different, then the equations have a unique solution..
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
The lines are parallel.
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).
They are parallel.
There are two equations in the question, not one. They are the equations of intersected lines, and their point of intersection is their common solution.
x=3
-6
None. When these two equations are graphed, the two lines are parallel. Since they never intersect, there is no point that satisfies both equations.
These are equations of two straight lines. Provided the equations are not of the same or parallel lines, there can be only one ordered pair. So the answer is - (not are) : (-1, 3).
