yes??

OpenStudy (jordanloveangel):

OpenStudy (danjs):

calculate the slope using the two points given

OpenStudy (danjs):

use both points, and that slope to find 2 equations

OpenStudy (jordanloveangel):

im thinking A and D

OpenStudy (danjs):

i dont know, didnt do it

OpenStudy (danjs):

slope = rise over run = (y2-y1) / (x2-x1)

OpenStudy (kendricklamar2014):

A is one of them

OpenStudy (danjs):

m = (-3-1) / (2-(-1)) = -4 / 3

OpenStudy (jordanloveangel):

for sure A @KendrickLamar2014

OpenStudy (danjs):

now use that slope in (y-y1) = m(x-x1) where (x1,y,1) = (-1,1) to get one equation

OpenStudy (danjs):

and then the other point to get the other equation

OpenStudy (jordanloveangel):

do D?

OpenStudy (jordanloveangel):

the right answers are A,B and D @KendrickLamar2014 and @DanJS
