consistent if their slopes are different
x+y=5
2x-3y=6
dependent if one equation is a multiple of the other.
2x+3y=9
4x+6y=18
inconsistent if the slopes are the same, but one equation is not a multiple of the other.
3x-y=8
9x-3y=5
x+y=5
2x-3y=6
dependent if one equation is a multiple of the other.
2x+3y=9
4x+6y=18
inconsistent if the slopes are the same, but one equation is not a multiple of the other.
