~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


            The answer  y%2B4=-2%28x%2B1%29  from the post by  @josgarithmetic is   T O T A L L Y   I N C O R R E C T.

            For your safety,  simply ignore it.

            The correct solution and correct answer are below. 


The equation in point-slope form is


    y - (-4) = 2*(x- (-1)).


It is the same as 


    y + 4 = 2*(x+1).    <<<---===  It is your final equation in the point-slope form.      ANSWER




Next transform it to the standard form 

    y = 2x + 2 - 4,

    y = 2x -2, 

    2x - y = 2.         <<<---===  It is your final equation in standard form.    ANSWER
