Question

Which of the following best describes the relationship between line x and line y?
Line x passes through (–3, –5) and (–7, –3).
Line y passes through (4, 7) and (12, 3).


A. neither perpendicular nor parallel

B. perpendicular

C. parallel

D. They are the same line.

Answer 1

Can anybody please help?

Answer 2

I'd get the lines equation first

Answer 3

then you can compare them, by looking at their slopes

Answer 4

come to think, you may just be able to do it by just getting the slopes only anyway

Answer 5

so, there, get the slopes and compare :), that'd tell you if they're perpendicular or parallel or whatever else

Answer 6

for line x I got 2/-4

Answer 7

for line y I got -4/8

Answer 8

ok, so 2/-4 => -1/2
-4/8 => -1/2

low and behold, they have the same slope!
perpendicular lines have the same slope, so

Answer 9

bah, parallel lines that is

Answer 10

not perpendicular
parallel lines have the same slope, and these 2 do

Answer 11

So the answer would be C? @jdoe0001

Answer 12

yes, they have the same slope, they're parallel with each other
