The answer is A with the slope being 3/2 and the y intercept being -5.
I believe the correct answer is B. I really hope this was the correct answer and helped you out.

Using number line, start with -3
-3 -1 = -4
-4 -1 = -5

-7 -1 = -8
-3 -4 -5 -6 -7 -8
Yes, because if you would draw 2 parallel lines in 3D space, a plane would exist between those two lines.
Hope this helps :)
