@Brittni0605 yours is good

anonymous · Answer

Ok, what do you know about the slopes of lines perpendicular to each other?

anonymous · Answer

@Brittni0605  they both have a 5?

anonymous · Answer

No, in general, how do you know lines are perpendicular by looking at their equations?

anonymous · Answer

@Brittni0605 umm honestly i dont know, im really bad at this

anonymous · Answer

alright, ill give you an example

anonymous · Answer

say you have the line y=2x

anonymous · Answer

which line is perpendicular to it? which line is parallel to it?

anonymous · Answer

@Brittni0605 Wait i think i got it, is it -5/2?

anonymous · Answer

a) y=2x-5
b)y=-1/2x+7
c)y=-2x-19

anonymous · Answer
