The Correct choice is ~
[tex]y = - 3x - 1[/tex]
Well, I will explain it if you want but I'm in hurry, so please bear with it ! but I assure you that the answer is correct !
Answer:
[tex]\mathsf{y=-3x-1}[/tex]
Step-by-step explanation:
[tex]\mathsf{(x_1,y_1)=(-1,2)}\\\\\mathsf{(x_2,y_2)=(1,-4)}[/tex]
[tex]\mathsf{slope \ (m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-4-2}{1+1}=-3}[/tex]
[tex]\mathsf{y-y_1=m(x-x_1)}[/tex]
[tex]\mathsf{y-2=-3(x+1)}[/tex]
[tex]\mathsf{y=-3x-1}[/tex]
