Answer:
{(−1,−1),(−7,−6),(−8,−2),(−10,−3)}
Step-by-step explanation:
we are given
y<0 and x≤y
so, we can write as

so, both values must be less than 0 or negative
we will verify each options
option-A:
Since, 
So, all solution satisfies
so, this is TRUE
option-B:
Since, 
x=-6 and y=-7
-7<-6
so, y<x
So, it does not satisfy solution
so, this is FALSE
option-C:
Since, solutions will be in points
intersection means interval
so, this is not valid solution
so, this is FALSE
option-D:
Since, 
So, all solution satisfies
so, this is TRUE
