Answer:
[(-15, 21), (-6, 12).(-1, 7)}
Step-by-step explanation:
we have
x+y=6
Find the values of y for XE (-15, -6, -1)
so
For x=-15
-15+y=6 --->y=21
therefore
a solution is the point (-15,21)
For x=-6
-6+y=6 --->y=12
therefore
a solution is the point (-6,12)
For x=-1
-1+y=6 --->y=7
therefore
a solution is the point (-1,7)
The set of ordered pairs that are solutions is
[(-15, 21), (-6, 12).(-1, 7)}
