help me @AriPotta

OpenStudy (brucebaner):

here are the points:(-4,1) (9,-2)

OpenStudy (brucebaner):

i got the answer but i just got to put it in standard form

OpenStudy (aripotta):

ok what did you get

OpenStudy (brucebaner):

the answer \[1-(-2)/(-4)-9\]

OpenStudy (aripotta):

that's just the slope

OpenStudy (brucebaner):

sorry about that

OpenStudy (brucebaner):

y-1=4/13=(x-9)

OpenStudy (aripotta):

1 - (-2) = 1 + 2 = 3 -4 - 9 = -13 so your slope is -3/13

OpenStudy (aripotta):

so y - 1 = -3/13(x + 4)

OpenStudy (brucebaner):

okay so the next step is?

OpenStudy (aripotta):

distribute the -3/13

OpenStudy (brucebaner):

-3/13x+-0.923

OpenStudy (aripotta):

yep so y - 1 = -3/13x - 0.923. now add 1 to both sides

OpenStudy (brucebaner):

y=-3/13+0.077

OpenStudy (aripotta):

add 3/13x to both sides

OpenStudy (brucebaner):

y+3/13x=0.077

OpenStudy (aripotta):

well 3/13x + y = 0.077 so since A can't be a fraction, multiply the whole equation by 13

OpenStudy (brucebaner):

3x+y=1.001

OpenStudy (aripotta):

y needs to be 13y

OpenStudy (aripotta):

so 3x + 13y = 1.001 is your answer

OpenStudy (brucebaner):

thx so much much

OpenStudy (aripotta):

no problem
