9) Chose A, B, or C from the list below.
4x+2y=8
Y=4-2x
A) Inconsistent
B) Consistent & Dependent
C) Consistent & Independent

If we add 2x to both sides of the lower equation then double each of it's terms we'll get the upper equation. These lines both have the same solution, so the system is consistent and dependent.
