Given equation is 7y+2=3x-5. Now we have to find which of the given point doesn't lies on the given line 7y+2=3x-5.

To find that we will just plug the given point and check if that point satisfies the given equation or not.


Check for (2,-1/7)

Plug it into 7y+2=3x-5.

7(-1/7)+2=3(2)-5

-1+2=6-5

1=1

Which is true hence this point lies on the given line 7y+2=3x-5.


Check for (3,-2/7)

Plug it into 7y+2=3x-5.

7(-2/7)+2=3(3)-5

-2+2=09-5

1=4

Which is False hence this point doesn't lies on the given line 7y+2=3x-5.


Check for (0,-1)

Plug it into 7y+2=3x-5.

7(-1)+2=3(0)-5

-7+2=0-5

-5=-5

Which is true hence this point lies on the given line 7y+2=3x-5.


Check for (1,-4/7)

Plug it into 7y+2=3x-5.

7(-4/7)+2=3(1)-5

-4+2=3-5

-2=-2

Which is true hence this point lies on the given line 7y+2=3x-5.


Check for (-1,-10/7)

Plug it into 7y+2=3x-5.

7(-10/7)+2=3(-1)-5

-10+2=-3-5

-8=-8

Which is true hence this point lies on the given line 7y+2=3x-5.


Hence final answer is (3,-2/7).
