Step-by-step explanation:
When x=-1
Substitute into the given equation
3 (-1) - 5y=19
-3-5y=19
Add 3 to both sides
-5y=22
Divide both sides by-5
y=-22/5
When x=0
3 (0) - 5y=19
0-5y=19
-5y=19
Divide both sides by-5
y=-19/5
When x=1
3 (1) - 5y=19
3-5y=19
Substrate 3 from both sides
-5y=16
Divide both sides by-5
y=-16/5
Therefore when x=-1, y=-22/5
When x=0, y=-19/5
When x=1, y=-16/5
