Question

How do you solve the system of equations by graphing and then classify the system as consistent or inconsistent `–3x + y = 2` and `–9x + 3y = 6`?

Answer 1

The system is incosistent.

Explanation:

To see that the system is inconsistent you only have to notice that the second equation is the first one multiplied by `3`, so the graphs of those equations would cover.
