C: D:x + y = 7

5x = 4y + 1

x + y = 7

4x = 5y - 1

A: x + y = 7

4x = 5y + 1

A: B:They are parallel lines

They will intersect in one point

If a system is consistent dependent, what canbe said about the graph of the system?

C: D:The lines are coincidental

They consistently need each other.

C: The lines are coincidental
