Answer:

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
