Parallel and Perpendicular Slope Practice

If I am looking for a line parallel to $y=-3x-2$  which one of these equations could it be?

•  $y=-2x-1$  

•  $y=3x-4$  

•  $y=-3x+6$  

•  $y=-2x-3$  

 $y=\frac{-2}{3}x+2$  and  $y=\frac{3}{2}x+9$  are what kind of lines?

• Parallel

• Perpendicular

• Neither
