Answer:
-1/2
Step-by-step explanation:
The point you want is (0,-2)
The slope of that line would be (4-(-2))/(-1-0)= -6
the line would be y= -6x-2
Answer: the third one

<h2>Solving the Question</h2>
We're given:
We can start by isolating one of the variables, like <em>y</em>:
![3x-y=-6\\-y=-3x-6\\y=3x+6](https://tex.z-dn.net/?f=3x-y%3D-6%5C%5C-y%3D-3x-6%5C%5Cy%3D3x%2B6)
Now we can find four solutions by plugging in any number for <em>x</em>:
![y=3x+6\\y=3(1)+6\\y=3+6\\y=9](https://tex.z-dn.net/?f=y%3D3x%2B6%5C%5Cy%3D3%281%29%2B6%5C%5Cy%3D3%2B6%5C%5Cy%3D9)
First solution: (1,9)
![y=3x+6\\y=3(2)+6\\y=6+6\\y=12](https://tex.z-dn.net/?f=y%3D3x%2B6%5C%5Cy%3D3%282%29%2B6%5C%5Cy%3D6%2B6%5C%5Cy%3D12)
Second solution: (2,12)
![y=3x+6\\y=3(3)+6\\y=9+6\\y=15](https://tex.z-dn.net/?f=y%3D3x%2B6%5C%5Cy%3D3%283%29%2B6%5C%5Cy%3D9%2B6%5C%5Cy%3D15)
Third solution: (3,15)
![y=3x+6\\y=3(4)+6\\y=12+6\\y=18](https://tex.z-dn.net/?f=y%3D3x%2B6%5C%5Cy%3D3%284%29%2B6%5C%5Cy%3D12%2B6%5C%5Cy%3D18)
Fourth solution: (4,18)
