@Luigi0210 help me

OpenStudy (diamondboy):

can u find d slope?

OpenStudy (luigi0210):

Yup, find the slope first, that'll give you m.

OpenStudy (anonymous):

slope is y=mx+b but, idk how im very terrible at slope like big time

@jigglypuff314 @Nnesha @Loser66 someone help plz

undeadknight26 (undeadknight26):

slope is y2 - y1/x2 - x1

jigglypuff314 (jigglypuff314):

try using the points (4, 16) and (6, 12)

undeadknight26 (undeadknight26):

What Emi said

|dw:1426035436363:dw| do I divide ?

jigglypuff314 (jigglypuff314):

not quite ^_^ 16 - 12 ------- 4 - 6

OpenStudy (anonymous):

4/-2

jigglypuff314 (jigglypuff314):

then divide :)

OpenStudy (anonymous):

it = -2 o.o

jigglypuff314 (jigglypuff314):

good :) so the slope is -2

jigglypuff314 (jigglypuff314):

then the y-intercept is where x = 0 http://prntscr.com/6fadq3 y-intercept = ?

OpenStudy (anonymous):

24

jigglypuff314 (jigglypuff314):

correct :) so slope = -2 y-intercept = 24 y = mx + b where m=slope and b=y-intercept plug them in ^_^

OpenStudy (anonymous):

y=-2x+24 ?

jigglypuff314 (jigglypuff314):

tah dahhhhh

OpenStudy (anonymous):

thank u c: <3

jigglypuff314 (jigglypuff314):

glad we could help ^_^
