Alright there are a few things to know when we are describing perpendicular lines. The most important thing to know is that two lines are perpendicular if their slopes are negative reciprocal of each other.

4. nincompoop

Let me give you an example. line 1 $$y = 3x + 2$$ line 2 $$y = \large -\frac{1}{3}x + 4$$ line 1 and 2 are perpendicular because the slopes are a negative reciprocal of another

5. anonymous

so is it A?

6. nincompoop

in the problem that you have, it would be awesome if you convert it into y-intercept form first because it will be pretty obvious once you do it.

7. anonymous

i already did and i got A... is that correct

@nincompoop

9. anonymous

u there? @nincompoop

10. nincompoop

will you show me how you determined A?

11. anonymous

how? my computer is not letting me draw it

12. nincompoop

you can type it

13. anonymous

i dont know how to type it out i just converted it into y-intercept form

14. nincompoop

that only gives you an idea of the slope tho, but how did you know that the line you picked contained the point (4, 1) ?

15. anonymous

im not good at english i just use google translate so i dont know how to exlain it typo

I am not going to tell you the answer to your problem. That is your job. I am merely here to show you how to understand the problem.

27. anonymous

i think its a but i need to know if im correct

28. nincompoop

if you solved it instead of GUESSED, then you have a better chance at learning.

29. anonymous

i solved it and i got A

30. nincompoop

then that must be the answer.

31. anonymous

k thx

32. anonymous

i cant believe i got it right
