Use (Y2Y1)/(X2X1) to find the slopes of each lines. If one is the negative reciprocal of the other, then they are perpendicular.

so is the answer a cause their slopes are different?

oh crap i meant C

Nikkibaby71410 Group TitleBest ResponseYou've already chosen the best response.0
cause if thier slopes are different then its not perpendicular. its C

omg fine give me a second!

So its 2/3

Nikkibaby71410 Group TitleBest ResponseYou've already chosen the best response.0
and since on is negative they are perpendicular?

Ok the slope of the first one is 2/3. What about the second one?

1/8

Nikkibaby71410 Group TitleBest ResponseYou've already chosen the best response.0
So 2/3 and 1/8 and those are perpendicular right cause one is a negative?

I thought if something had the same slope than meant it was perpendicular?

BluFoot Group TitleBest ResponseYou've already chosen the best response.1
They're not perpendicular because one is not the negative reciprocal of the other.

BluFoot Group TitleBest ResponseYou've already chosen the best response.1
If they were 2/3 and 3/2, they would be perpendicular. Or 7/8 and 8/7. Or 15/100 and 100/15

Same slope = parallel

what exactly does that mean . i feel so dumb im 18 and dont know this pellet

BluFoot Group TitleBest ResponseYou've already chosen the best response.1
Negative reciprocal means you invert the fraction and make it negative. So can you find the negative reciprocal of 5/6?

Good :) So if the slopes aren't negative reciprocals of each other, they're not perpendicular!
