Answer:
[tex] - \frac{1}{2} [/tex]
Step-by-step explanation:
starting from (0,1) it shifts down 1 unit and shifts to the right 2 units to get to (2,0)
from (2,0) shift down 1 unit and shift to the right 2 units to get to (4,-1) and so forth
shifting down 1 unit = -1 (y axis)
shifting to the right 2 units = 2 (x axis)
gradient:
y/x = -1/2
