Is y=5/3x+3,20x+12y=12 a parallel, perpendicular. or a neither pair equation

Neither

Step-by-step explanation:

y = 5/3 x + 3, this line has slope = 5/3

20x + 12y = 12

12y = - 20x + 12

y = - 20/12 x + 1

y = - 5/3 x + 1, this line has slope = - 5/3

Parralel; same slopes

Perpendicular; slopes are opposite and reciprocal

So answer is neither pair parallel nor perpendicular
