(1,-8) sorry if you needed an explanation i am not good at that. Hope this helped!!
No it is C-2,-3 D-2,5 hope this helps
Line Q's equation would be y=1/2x+3 and line S's equation is Y=1/2x-2. You would compare them. So you would get 1/2x+3=1/2X-2. Subtract 1/2X from both sides and you get 3=-2. So the answer is these lines have no solution.
