Answer:

The answer to your question is letter C

Step-by-step explanation:

Process

1.- Find two points of the line

   A ( 0, 1)

   B ( 1, -3)

2.- Find the slope of the line

    [tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

    [tex]m = \frac{-3 - 1}{1 - 0}[/tex]

    [tex]m = \frac{-4}{1}[/tex]

           m = -4

3.- Find the equation of the line

            y - y1 = m (x - x1)

            y - 1 = -4( x - 0)

            y -1 = -4x

            y = -4x + 1
