Answer:
Only 1st option Negative three-fourths divided by Negative two-thirds has positive quotient.
Option A is correct.
Step-by-step explanation:
We will solve to find out Which expression has a positive quotient.
We know the division rule:
and 
We will use these rules
1) Negative three-fourths divided by Negative two-thirds

The quotient is positive.
2) Negative StartFraction 1 over 8 EndFraction divided by 3 and one-fifth

The quotient is negative.
3) 2 and StartFraction 2 over 7 EndFraction divided by negative one-fifth

The quotient is negative.
4) Negative 6 divided by Five-thirds

The quotient is negative.
So, only 1st option Negative three-fourths divided by Negative two-thirds has positive quotient.
Option A is correct.

Answer:
y=3/4x-4
Step-by-step explanation:
The form is y=mx+b so isolate y
-4y=16-3x
y=-16/4-3x/-4
y=3/4x-4
M=2/5 , (0,3)
use y= mx+c , find c first.
-3 = (2/5) 0 + c
c = -3
Thus the equation will be y=(2/5)x - 3.
or in some case,
(y1-y)=m(x1-x)
(-3-y)=(2/5)(0-x)
