(Points : 2)

Inconsistent


Cannot be determined

Answer 1

can u define consistent/inconsistent? first time im hearing the terms..

Answer 2

If you say a system is consistent, it means that it can be solved.
If you say a system is inconsistent, it means that the system has no solution.

Answer 5

just had to post that.. back to the problem

Answer 6

lol

Answer 7

y = -1/2x - 1 and y = 3x + 3
set them equal to each other and try solving:
(-1/2)x - 1 = 3x+3
x + 2 = -6x - 6
x+6x = -6-2
7x = -8
x = -8/7
I can solve it, so it must be consistent.

Answer 8

thanks!
