Answer 3

do you know what point slope form is?

Answer 4

I think I have it y+1=6(x+8)

Answer 5

you have it backwards switch the 1 and 8

Answer 6

you're very close! But you mixed up your x and y points that you subbed in :)
Remember point slope is:
y - y1 = m ( x - x1)

So we know slope (m) = 6 , and it passes through the point (-1, -8)
So x1 = -1 and y1 = -8

therefore when we sub it into the point-slope formula.. we get:

y - ( -8) = 6 ( x - (-1))

y + 8 = 6 ( x + 1)

Thanks!

Answer 8

no problem! :)
