aravindg · Answer

use two point form

anonymous · Answer

m= (x2-x1)/(y2-y1)?

^this is exactly what I did. I ended up with the answer:y= (21/2)x+15 and it's wrong.

anonymous · Answer

i'm redoing it i think i see my problem.

anonymous · Answer

My answer this time is (21/2)x + 28 and I don't see where I'm going wrong.

dumbcow · Answer

your slope is wrong
$$m = \frac{y_{2} -y_{1}}{x_{2} -x_{1}}$$
change in 'y' is on top

aravindg · Answer

yep :)

anonymous · Answer

yeah i noticed that after i typed it in.but  i have been doing your formula the whole time on my whiteboard and still getting it wrong

dumbcow · Answer

ok, using the given points
$$m = \frac{84}{14} = 6$$
then
$$y - 7 = 6(x-(-8))$$
$$y-7 = 6x+48$$
$$y=6x+55$$
