-3/2

4

Step-by-step explanation:

Take the points on the graph

(30,60) and (50,30)

and use the slope formula

m =(y2-y1)/(x2-x1)

    = (30 - 60)/(50 - 30)

  = -30/20

  = -3/2

The same technique is used for the data points

m =(y2-y1)/(x2-x1)

   = (16-12)/(4-3)

   = 4/1

   = 4

b) the dogs need to shift their focus to human scent.
