    Answer: y + 4 = -3(x+1)

    Step-by-step explanation:

    We need to rewrite in form of y=mx+b.

    3x+y=5

         y = -3x + 5  

    The slope is -3.

    In addition, the slope of two parallel line would be equal, the slope of the line would be -3.

    y- y1 = m(x- x1)

    y- (-4) = -3(x – -1)

    y + 4 = -3(x+1)
