• nothing

What does the "b" represent in  $y=mx+b$  

• y-intercept

• nothing

• slope

• base

Slopes of parallel lines are...

• opposite reciprocals

• the same

• opposites

• always 7

Slopes of perpendicular lines are...

• opposite reciprocals

• the same

• opposite

• always 7

 $y=\frac{-2}{7}x+4$  and  $y=\frac{7}{2}x-3$  are parallel lines

• True

• False

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

•  $y=-2x-1$  

•  $y=3x-4$  

•  $y=-3x+6$  

•  $y=-2x-3$  

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

• the same line

• perpendicular

• neither

• parallel

 $-6x+y=2$  and  $6x+y=2$  

• Parallel

• Perpendicular

• Neither

 $y=\frac{-2}{3}x+2$  and  $y=\frac{3}{2}x+9$  

• Parallel

• Perpendicular

• Neither

Are these lines parallel?
