Question

Which change could result in 2 parallel lines?

*picture will be provided below*

decrease the slope of line m

decrease the slope of line n

both

neither

Answer 1

Picture:

Answer 2

A decrease in the slope of line n could surely create parallel lines. Now, maybe if we decrease the slope of line m, we could get anti-parallel lines, but I am unsure of the second part. Honestly, I would wait for a second opinion :-)

Answer 3

Do u think it is both? ^^

Answer 4

I think, that, by definition of a parallel only, only a decrease in the slope of line n. But if anti-parallelism counts, then both. Personally, I would go for only the slope of n. Anyway, try to get a second opinion on this :-)

Answer 5

Anyone else? :P

Answer 6

B might be

Answer 7

Disregard what I said. I thought something different about anti parallel lines. I would say both.

Answer 8

though if you keep decreasing the slope of m, even after zero , you will get the same result,
i think, both might be right.

Answer 9

Anyone else? :P

Answer 10

parallel lines: lines that never cross because they are always the same distance apart

Answer 11

both

Answer 12

thanks everyone :) anyone else would like to answer? :P

Answer 13

Given that the two lies intersect and assuming that does not change, I now think the answer is "neither." I took two pens and arranged them to model the diagram. Then, I moved them about while maintaining their point of intersection. Of course, they never became parallel.
