It can be solved in a number of ways.

1) if you consider x= -3, then the Y= 5(-3)=> -15.

2) if you consider x=0, then Y=5(0)=> 0.

3) if you consider x=2, then Y=5(2)=> 10.

1) if you consider x= -3, then the Y= 5(-3)=> -15.

2) if you consider x=0, then Y=5(0)=> 0.

3) if you consider x=2, then Y=5(2)=> 10.
