Question

Given the equation 4x + 2y = 9, which equation below would cause an inconsistent-independent system?
A. 6x + 12y = 13
B. 2x + y = -6
C. x - 2y = 7
D. 8x - 4y = -5

Answer 1

8x - 4y = -5 <- this one isn't it, the slope is different

2x + y = -6 (*2)
4x + 2y = -12
^
this one looks exactly the same like the one in the problem statement
it has a different solution even though it has the same amounts of y, x
that means there's a contradiction and the system is inconsistent

Answer 2

so which one would it be?

Answer 3

B
