Answer:

  resultant r is shown in the attached

Step-by-step explanation:

The resultant of the sum of vectors has components that are the sum of the components of the contributing vectors.

  a = (-1, -3)

  b = (2, -1)

  r = a +b = (-1, -3) +(2, -1)

  r = (-1 +2, -3 -1) = (1, -4)

The resultant vector can be drawn from the origin to the point (1, -4), as it is in the attachment.
