SOLUTION: Solve the system of equations by graphing. Then classify the system as consistent or inconsistent; and the equations as dependent or independent. y= -x-12 8x-7y=9 Again can so

Question 137492: Solve the system of equations by graphing. Then classify the system as consistent or inconsistent; and the equations as dependent or independent.
y= -x-12
8x-7y=9
Again can someone help me with this one. This class is getting so much harder than I ever expected.

Solve the system of equations by graphing. Then classify the system as consistent or inconsistent; and the equations as dependent or independent.
y= -x-12
8x-7y=9
--------------
y = -x-12
y = (8/7)x-(9/7)
----------
slopes are different and y=intercepts are different so the
system in consistent:
