Answer:

  3

Step-by-step explanation:

The slope of the line shown can be found from the formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (0 -1)/(0 -(-3)) = -1/3

Any line perpendicular to this will have a slope that is the opposite of the reciprocal of m. Its slope will be ...

  -1/m = -1/(-1/3) = 3

Every perpendicular line will have a slope of 3.
