Question 281182
Imagine you want to add a sprinkler system and the location of one section of the sprinkler line can be described by the equation 
y=-1/2x-4 
Complete the table for this equation. 
x y (x,y)
___ -1

y = (-1/2)x - 4
---
-1 = (-1/2)x - 4
3 = (-1/2)x
x = -6
--------------------------------
y=(-1/2)x-4
-2 ___

y = (-1/2)(-2) - 4
y = 1-4
y = -3
---------------------------------
y=(-1/2)x-4
___ -4 

-4 = (-1/2)x -4
0 = (-1/2)x
x = 0
---------------------------------
y=-1/2x-4

2 ___
y = (-1/2)2 -4
y = -1-4
y = -5
---------------------------------
y=(-1/2)x-4

8 ___ 
y = (-1/2)8-4
y = -8
