Which line has a slope of 0? A: x = 1 B: 3y + 6x = 0 C: y = x D: y = -5

D) y=-5

Step-by-step explanation:

I believe the answer is no solution.
turn x-2y=-8 into x=2y-8 and then substitute into the other equation. this becomes 3(2y-8)-6y=-12. simplify to 6y-24-6y=-12. the 6y-6y cancels each other out, leaving -24=-12. -24 does not equal -12, so therefore there is no solution. since there is no solution, we can then assume that the lines do not intersect and that they are parallel.
