isolted both 'y's', then you'll get a hint

anonymous · Answer

How would I isolate the y

hero · Answer

Well, you should decide which you want to figure out first, part a or part b?

anonymous · Answer

Lets say I want to solve part a first how would I start

anonymous · Answer

when you isolated y ( which ill leave to you ) if the number next to x ( called the slope),  is the same for both  equestions, the lines are parallel.  If one is a flip of the other and with the opposite sign, the lines are perpendicular

hero · Answer

I don't even know why you're here bro. You have no intention of helping her.
