All we have to do, is plug in the ordered pairs, and see which ones are true to the equation. (x,y)
(1,0) After plugging those into the equation we get: 2<-1. this is not true, so this answer is false.
I continued this all the way down the line:
(0,1)= 1<-1 = false
(0,-1)=-1<-1=false
(-1,0)= -2<-1=true
(3,2)=-1<-1=false
(-2,-4)=2<-1=false
(2,4)=2<-1=false
(-4,2)=8<-1=false
(0,0)=0<-1=false
There is only one true ordered pair for this equation:
(-1,0)
