Select the equations that are parallel and perpendicular to y = x + 5 and that pass through the point (-2, -1).

parallel: y = x - 1
perpendicular: y = -x + 1

parallel: y = -x - 1
perpendicular: y = x + 2

parallel: y = x + 1
perpendicular: y = -x - 3

parallel: y = 2x - 2
perpendicular: y = -2x - 1

What do we know about the slopes of parallel and perpendicular lines?

anonymous · Answer

That's just it, I am not sure what to do. That's why this question is here :/

anonymous · Answer

That is why I am asking you a more specific question, specifically about the slopes.  What do we know about the slopes of parallel lines, and what do we know about the slopes of perpendicular lines?

anonymous · Answer

I don't know anything about it. D:
