Answer 1

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

Answer 2

How would I isolate the y

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

@Luis_Rivera she wanted to know how to isolate y.

Answer 7

Then stop staring at the question and show her
