Question

I need help with Algebra 1 !!!

What are parallel and perpendicular lines? How can you tell the difference between the two, and what are regular slopes? Show examples.

Answer 1

Parallel Lines - http://www.mathsisfun.com/definitions/parallel-lines.html
Perpendicular Lines - http://www.mathsisfun.com/definitions/perpendicular.html

I am finding a link for regular slopes. All I am getting is crossword puzzles O_O

Answer 2

no @OpiGeode this is a homework help study website

Answer 3

I am looking for someone to help me. I don't know what parallel and perpendicular lines are. Nor how to identify them :/

Answer 4

Answer 5

parallel have the same slope and they look the same and go the same way
perpendiculars intersect and form an x form

Answer 6

oh and perpendicular lines have opposite reciprocal slopes means if one slope is 2 the other slope will be -1/2

Answer 7

So the lines -3 and 3 are parallel?

Answer 8

no because parallel lines have the same everything including slop they are like mirror images

Answer 9

so -3 and 3 would be neither perp or parallel?

Answer 10

yup unless the 3 was 1/3 which would make it perpendicular

Answer 11

Perp would be -4 and 1/4 or 10/12 and -1 1/5

Answer 12

Oh no wait, not the second one

Answer 13

-4 and 1/4 is perpendicular and the other ones dont have the same slope nor are they opposite reciprocals

Answer 14

and parallel would be like 1/2 and 1/2?

Answer 15

yes because they are the same

Answer 16

So my homework is asking me to write the equation of a line parallel to y = 1/3x - 2

That would basically be something like: y = 1/3x - 4

Answer 17

Same slope, just different y intercept?

Answer 18

exactly! :D

Answer 19

and then it also says to write one perpendicular for the same line: y = 1/3x - 2

That would be..... y = -3x -2 ?

Answer 20

as long as the lines look like mirror images and dont touch they are parallel

Answer 21

YES!

Answer 22

you got it :0

Answer 23

:)

Answer 24

Umm, I think I am starting to get the concept, but can I just post what I get for some questions and you check them real quick?

Answer 25

sure just tag me
