I'm having trouble on these questions. 4x + 6y = -12 2x + 3y = 9 x + y = -4 -3x + 2y = 2 x + y = -1 4x + 4y = -4 x - y = -2 3x - y = 0 x - 4y = -8 2x - 3y = -16

Turn them into slope intercept form (y=mx+b). That will help. For example, one of the sets has the same equation twice (just in different forms), and another has two parallel lines that never intersect.
are all four separate or one is pair the problem and the other 4 are answers?
No those are all problems the answers I have to choose from are Which system has (-8, 0) as the solution? Which system has infinite solutions? Which system has (1, 3) as the solution? Which system has (-2, -2) as the solution? Which system has no solutions?
