Answer:
The range is [9,-3,-9]
Step-by-step explanation:
we have the relation
[tex]3x+y=3[/tex]
To find the range determine the value of y for each value of x in the relation
so
For x=-2
substitute in the equation
[tex]3(-2)+y=3[/tex]
[tex]-6+y=3[/tex]
[tex]y=9[/tex]
For x=2
substitute in the equation
[tex]3(2)+y=3[/tex]
[tex]6+y=3[/tex]
[tex]y=-3[/tex]
For x=4
substitute in the equation
[tex]3(4)+y=3[/tex]
[tex]12+y=3[/tex]
[tex]y=-9[/tex]
therefore
The range is [9,-3,-9]
