Question 143033
Suppose you want to add a sprinkler system, and the location of one section of the sprinkler line can be described by the equation

 y = -(1/2)x-4

Complete the table for this equation. 
if x = -2 then y = -(1/2)*-2-4 = 1-4 = -3 and(x,y)= (-2,-3)
-----------------------
if x = (what) then y= -4 and (x,y)= (what)
-4 = (-1/2)x -4
(-1/2)x) = 0 
x = 0
So, if x = 0,then y = -4 and (x,y) = (0,-4)
---------------------------
if x = 2 then y = -(1/2)*2-4 = -5 and(x,y)= (2,-5)
--------------------------------
if x = 8 then y = -(1/2)*8-4 = -4-4=-8, and (x,y)= (8,-8)
