The standard form, parametric equation and vector form have simple analogies for 3 or more dimensions.
Then they are simultaneous 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).
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 ordered pair is - not are : (0.5, -1)
For vertical lines, when you try to figure out the slope, you get zero in the denominator - in other words, a division by zero.
Yes. But for what?
If you mean 3x+2y = -5 and -2x+3y = -5 then they are straight line equations
Then they are simultaneous equations.
Invisible lines!
What do you call equations describing two or more lines
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).
The two equations represent the same straight line.
That they, along with the equations, are invisible!
They are simultaneous 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 ordered pair is - not are : (0.5, -1)
Its called Simultaneous Equations
If you refer to linear equations, graphed as straight lines, two inconsistent equations would result in two parallel lines.
one solution; the lines that represent the equations intersect an infinite number of solution; the lines coincide, or no solution; the lines are parallel
