Question 201974: x - y = 10
x - y = -2
What is the ordered pair?
Is the system consistent or inconsistent?
Is it dependent or independent?
Can someone also give me a break down of how to do this because I am very confused! Thank you!: Solve the system of equations by graphing. Then classify the system.

You can put this solution on YOUR website!
x - y = 10
x - y = -2
What is the ordered pair?
Is the system consistent or inconsistent?
Is it dependent or independent?
-------------------------------------------------------
Subtract one equation from the other to get:
0 = 12
That is a contradiction meaning the variable values
do not have the same meaning in the two equations.
The equations are inconsistent.
-----------
Putting the equations in slope intercept form you get:
y = x-10
y = x+ 2
--------------
Both equations have the same slope (m = 1)
but the y-intercepts are different; so the
lines are parallel; therefore the system
is independent.
