find an equation of the line containing the given pair of points {1/6,-1/3} and {5/6,3)

OpenStudy (anonymous):

remember the formula for the slope?

OpenStudy (anonymous):

lets start here. do you remember the slope formula? if you do, write it, if not say no.

OpenStudy (anonymous):

no

OpenStudy (anonymous):

ok, the formula for the slope is (y(2)-y(1))/(x(2)-x(1)) so if we use point 1 as {1/6, -1/3} and point 2 as {5/6, 3} what would our equation be, keeping in mind that both points are written as {x,y}

OpenStudy (anonymous):

man, I have not a clue

OpenStudy (anonymous):

ok, how about if i tell you that point 1 = { x(1) , y(1) } = { 1/6 , 1/3 } point 2 = { x(2) , y(2) } = { 5/6 , 3 }

OpenStudy (anonymous):

the answer is 5x-7/6

OpenStudy (anonymous):

(3- (1/3)) / ((5/6)-(1/6))

OpenStudy (anonymous):

solve that real quick-like

OpenStudy (anonymous):

Hmm... maybe this will help: (\[(x _{1},y_{2}) = { 1/6 , 1/3 }\]

OpenStudy (anonymous):

DOPE! I meant to say y1 on that example. :(

OpenStudy (anonymous):

Plus, it should even be NEGATIVE 1/3. Sheesh.

OpenStudy (anonymous):

lol, it's all good, i don't think he is interested in anything but the answers anyway

OpenStudy (anonymous):

yes, because i have a small amount of time until the thunderstorm knocks my electric out, and i fail the test because i cant complete it

OpenStudy (anonymous):

Well, how about all three of us work together on the other problem that we're working on? http://openstudy.com/groups/mathematics#/groups/mathematics/updates/4e2bb78d0b8b3d38d3ba2505
