Hmmm you seem familiar :D
Okay let's get started Okay so remember that if two lines are parallel then the slopes must be exactly the same (ex: -4 and -4) if two lines are perpendicular then the slopes are negative reciprocals (ex: -4 and 1/4)
y = -3x + 7 -2x + 6y = 3
y = (x/3) + 1/2
So these two are perpendicular since the slopes negative reciprocals
y = (x/5) + 6 -2x + 10y = 5
y = (x/5) + 1/2
So these lines are parallel since the slopes are exactly equal
I hope this helps!
