Question

is P(1,-2) Q(10,1) R(2,-8) S(-7,-5) Parallel or perpendicular or neither

Answer 1

four points?

Answer 2

?

Answer 3

are there lines?

Answer 4

no, the question is just are PQ and RS parallel, perpendicular or neither

Answer 5

oh ok so the lines are PQ and RS

Answer 6

oh, yes, I am sorry
this is all new to me, and I am not sure how to answer this questions

Answer 7

do you know how to find the slope between two points?

Answer 8

if two lines have the same slope, then they are parallel

Answer 9

oh, ok, yes

Answer 10

if the slopes are, say \(m_1,m_2\)

in the case that the lines are perpendicular

\[m_1=-1/m_2\]

Answer 11

P(1,-2) Q(10,1)
What is the slope of the first line PQ?

Answer 12

this is where I am having problems. This stuff is all new to me and I am having a hard time understanding it

Answer 13

ok ill show you how to find
The slope between two points

Answer 14

ok, thank you

Answer 15

ok see
