You can put this solution on YOUR website! To answer the table question, just replace x with every value given for x and solve for y. This will give you 5 different points in the form (x,y) to complete the table of x and y values.
The question "What objects might be in the way as you lay the pipe for the sprinkler?" means nothing without more detail.

You can put this solution on YOUR website! 
x=_,-2,_,2,8
y=-1,_,-4,_,_
if y=-1 then  add 4
 multiply by -2
if x=-2 then 
if y=-4 then  add 4
if x=2 then 
if x=8 then 
x=-6,-2,0,2,8
y=-1,-3,-4,-5,-8
