studygurl14 · Answer

find the slope of each line using the points given, then if the slopes are equal, then the lines are parallel

anonymous · Answer

i can remember- how do u find the slope?

anonymous · Answer

*cant

undeadknight26 · Answer

isn't the slop 7 and 3?  for these points?

anonymous · Answer

howd u find that?

studygurl14 · Answer

$$m = \frac{ y _{2} - y _{1} }{ x _{2} - x_{1} }$$
m = slope

anonymous · Answer

ahhh! ok

anonymous · Answer

hold on can u check my answer?

studygurl14 · Answer

sure

undeadknight26 · Answer

oi i forgot that...lol i just learned it like a few weeks ago too...

anonymous · Answer

srry- just a sec

anonymous · Answer

they arent parallel
the first slope was -1/-1 and the second slope was 3/4
is this correct?

studygurl14 · Answer

the first slope was actually - 6, and the second was 3/4

But yeah, they aren't parallel

oh i see wat is did wrong thank you!
