@DaBest21

OpenStudy (anonymous):

im here

OpenStudy (i_love_my_nieces):

Can you look over my question please?

OpenStudy (anonymous):

i am

OpenStudy (anonymous):

well first can u find the negative rciprocal

OpenStudy (i_love_my_nieces):

-2?

OpenStudy (anonymous):

wait never mind i got a different answer than the choices

OpenStudy (irishboy123):

@I_love_my_nieces how are we going to do this?

OpenStudy (i_love_my_nieces):

I don't know that is why I posted it

OpenStudy (irishboy123):

so straight lines are ordinarily described as \(y =mx + c \) or as \(y-y_o = m (x - x_o)\) i think you are experiencing the latter.

OpenStudy (i_love_my_nieces):

the latter?

OpenStudy (irishboy123):

\(y-y_o = m (x - x_o)\) \(m = \dfrac{y-y_o}{x-x_o}\)

OpenStudy (anonymous):

the latter means the last said

OpenStudy (i_love_my_nieces):

I know I PMed you

OpenStudy (i_love_my_nieces):

OK so what will my answer be

OpenStudy (i_love_my_nieces):

@M0j0jojo

OpenStudy (i_love_my_nieces):

Is it option A?

OpenStudy (i_love_my_nieces):

Guys I really need this answer ASAP

OpenStudy (anonymous):

You just take the perpendicular slope. everything else stays the same. the original slope is 8/3 the and perpendicular slope is -3/8. So the answer will be \[y-3=\frac{ -3 }{ 8 }(x+2)\]

OpenStudy (mathmale):

You're given the equation of a line. Your job is to extract the slope of the given line and from it obtain the slope of a line perpendicular to the given line. Can you do that? The slope of the given line is ___________ The slope of a line perpendicular to the given line is the negative reciprocal of the slope of the given line. OK so far?

OpenStudy (mathmale):

M0j0jojo's approach is interesting and will "work." But you still need to understand that if two lines are perpendicular, their slopes are negative reciprocals of one another.
