Put the 2nd equation into Standard () form.

If you have a system of equations

And where

if

, , and

then the system is consistent and dependent.

But if

, , and

then the system is inconsistent.

Otherwise the system is consistent and independent.

6x + 3y = 9
divide by3
y+2x=3
y = � 2x + 2
y+2x=2
...

they are parallel lines
No solution
inconsistent
