aripotta · Answer

ok, first put it into point-slope form and then rewrite it into slope-intercept

aripotta · Answer

point-slope: y - y1 = m(x - x1)

anonymous · Answer

how do you know which number goes where?

aripotta · Answer

all coordinates are setup as (x,y)

aripotta · Answer

so the first number in the pair would be x1

aripotta · Answer

and the second would be y1

aripotta · Answer

and of course, m is whatever the slope is

anonymous · Answer

it would be B? right?

aripotta · Answer

no

anonymous · Answer

ohh, i think i fied my problem but mybe not. they way i have it worked out it should be A

anonymous · Answer

fixed**

aripotta · Answer
