Question 146448: Solve the systems of equations by graphing. Then classify the system as consistent or inconsistent and the equations as dependent or independent
2x-6y=42
3x-9x=-21

Inconsistent system, no solution.
Divide eq. 1.by 2, you get,
x-3y=21
Divide eq. 2 by 3, you get,
x-3y=-7
That leads to the statement
21=-7
