84 divided into sevenths could either be:
84 x (1/7) or simply 84/7
In the end, the answer would be 12.
i dont have time to do all of it (sorry)
but this is how you do the point and slope questions:
use the equation: y-y1 = m(x - x1)
y1 is the y point you are given
x1 is the x point you are given
m is your slope
substitute all of those in from the question
the first one is:
y --4 = -5/6(x-8)
-- turns into a plus so the answer would be
y+4 = -5/6(x-8)
The angle vertical to it is DF
42 divided by 6 is 7. if you subtract 4 from 7 the answer would be 3
I believe the answer is D
