Please help me answer this I don't understand, I would really appreciate how you solved it as well.

Answer: Parallel
Step-by-step explanation:
Set your -2x+10y=5 equation equal to y
-2x+10y=5
-10y -10y
-2x=5-10y
-5 -5
-2x-5+-10y
-10 -10 -10
-1/5x-1/2=y
Now you can put your equations into your graphing calculator and examine the lines made
(if you dont have one search up online graphing calculator on google or your app store)
