y=+-%281%2F2%29x-3
Complete the table for this equation.
(x,y)
if y=-1: -1=+-%281%2F2%29x-3...>...-1%2B3=+-%281%2F2%29x...>...2=+-%281%2F2%29x...>...4=+-x...>...-4=+x

if x=-2: y=+-%281%2F2%29%28-2%29-3...>...y=+1-3...>...y=+-2

if y=-4: -4=+-%281%2F2%29x-3...>...-4%2B3=+-%281%2F2%29x...>...-1=+-%281%2F2%29x...>...-2=+-x...>...2=+x

if x=6: y=+-%281%2F2%29%286%29-3...>...y=+-3-3...>...y=+-6
if x=8: y=+-%281%2F2%29%288%29-3...>...y=+-4-3...>...y=+-7

so, you have:
x |y
-4 |-1
-2 |-2
2 |-4
6 |-6
8 |-7
