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  $y=\frac{3}{2}x+9$  

• Parallel

• Perpendicular

• Neither

What is the slope of the line perpendicular to the line y=3x+7?

• 7x

• 1/3

• 4

• 1/2

• 2

• 3

y = 3x +2
y = 3x - 3
These lines are...
