how to find the slope of the two points G (2,6) and H(4,-2), how to solve?

OpenStudy (karatechopper):

y-y/x-x

OpenStudy (amistre64):

g-h; and stack y/x

OpenStudy (anonymous):

Do the bigger numbers get subtracted from, or there's a certain order?

OpenStudy (amistre64):

G (2,6) -H (4,-2) --------- (-2,8); 8/-2

OpenStudy (amistre64):

doesnt matter, pick one and subtract it from the other

OpenStudy (anonymous):

That's in all cases right?

OpenStudy (amistre64):

no, it only works for this one problem :)

OpenStudy (anonymous):

Oh, what would I do for other problems?

OpenStudy (amistre64):

yes, for all cases of finding slope from 2 points this works fine

OpenStudy (amistre64):

see jennamays problem up top? find slope between 2 points? same process

OpenStudy (anonymous):

So there's no certain way to choose which number is subtracted from?

OpenStudy (anonymous):

You just pick one at random?

OpenStudy (amistre64):

stack your points like I did to avoid any confusion

OpenStudy (amistre64):

G (2,6) -H (4,-2) --------- (-2,8); 8/-2 OR H(4,-2) - G (2,6) --------- (2,-8); -8/2

OpenStudy (anonymous):

That goes for all problems right? Like for C (2,-1) and D(4,3)?

OpenStudy (amistre64):

yep, try it out

OpenStudy (amistre64):

c-d OR d-c ... doesnt matter

OpenStudy (anonymous):

Ohh I see, it works for non-negative ones too correct? A(1,2) and B(10,5)?

OpenStudy (amistre64):

yep, a point is a point is a point.

OpenStudy (amistre64):

subtract one point from the other and stack y/x :)

OpenStudy (anonymous):

subtract one point from the other?

OpenStudy (amistre64):

give it a shot so I can see how your interpreting my instructions

OpenStudy (anonymous):

A(1,2) B(10,5) ________ -9 ---- -3 3 --- 1 OR B(10,5) A(1,2) _______ 9 -- 3 3 -- 1

OpenStudy (amistre64):

very good

OpenStudy (amistre64):

but stack y/x

OpenStudy (anonymous):

Thanks, I always thought there was some tricky math magic involved with slope that I never got :P Thanks again

OpenStudy (amistre64):

y = 3 x = 9 in this case

OpenStudy (anonymous):

Yea
